Comments: 19 pages, Nishinomiya-Yukawa Symposium Bol'shoi i dostupnyi obzor po ekzoplanetam. Tablic net. Vse dannye privedeny v ponyatnoi graficheskoi forme. astro-ph/0505004 Kosmicheskaya mimikriya: ne yavlyaetsya li lyambda-CDM model' zamaskirovannym mirom na brane? (Cosmic Mimicry: Is LCDM a Braneworld in Disguise ?) Authors: Varun Sahni, Yuri Shtanov, Alexander Viznyuk Comments: 20 pages, 4 figures Na segodnyashnei den' standartnoi model'yu yavlyaetsya t.n. lyambda-CDM. Ona vklyuchaet v sebya vklad temnoi energii (lyambda) i holodnoi temnoi materii (CDM). Osnovnye "parametry Vselennoi", kotorye vy vstrechaete v populyarnyh stat'yah i obzorah, polucheny kak raz v ramkah etoi modeli. Odnako .... Odnako "zhizn' - eto slozhnaya shtuka" (s). Vpolne mozhet byt', chto my zhivem na brane. I "mir na brane" (braneworld) mozhet mimkrirovat', maskirovat'sya tak, chto my budem schitat', chto rabotaet imenno lyambda-CDM model' v ee standartnom vide. Varun Sahni (kstati, vypusknik GAISh) i ego soavtory kak raz detal'no razbirayut vozmozhnost' takoi "kosmicheskoi mimikrii". astro-ph/0505005 Antropnyi princip i prodolzhitel'nost' kosmologicheskogo proshlogo (The Anthropic Principle and the Duration of the Cosmological Past) Authors: Milan M. Cirkovic Comments: 45 pages, 1 figure Stat'ei pod schastlivym nomerom 0505005 okazalsya ocherednoi opus Milana Cirkovicha. Dannaya tematika vsegda vyzyvaet interes, poetomu s chistym serdcem rekomenduem stat'yu k prochteniyu. Sm. takzhe druguyu svezhuyu rabotu etogo avtora Too Early? On the Apparent Conflict of Astrobiology and Cosmology. astro-ph/0505007 O vozmozhnosti togo, chto pary neitronnyh zvezd i chernyh dyr otvetstvenny za gamma-vspleski (On the viability of neutron star black hole binaries as central engines of gamma-ray bursts) Authors: S. Rosswog Comments: 8 pages, 2 Figures Kak vy pomnite, gamma-vspleski delyatsya na korotkie (menee odnoi sekundy) i dlinnye (bolee 10 sekund) (sm. risunok po ssylke). Pervye ob'yasnyayutsya kak rezul'tat sliyaniya dvuh neitronnyh zvezd (i my nedavno rasskazyvali ob etom, eto byl kak raz obzor Stefana Rossvoga). Vtorye - akkreciei na chernuyu dyru posle vspyshki sverh(giper)novoi. Rezonno sprosit': a chto budet, esli slivaetsya neitronnaya zvezda i chernaya dyra? Ochevidno, chto neitronnaya zvezda budet razrushena, i vokrug chernoi dyry obrazuetsya disk. Situaciya kachestvenno pohozha na tu, chto schitaetsya prichinoi gamma-vspleska. Stefan detal'no (naskol'ko eto seichas vozmozhno) issleduet sliyaniya neitronnyh zvezd i chernyh dyr. Ego rezul'taty govoryat o tom, chto svoistva obrazuyushihsya diskov ne pozvolyayut govorit' o generacii gamma-vspleskov. Drugaya stat'ya na tu zhe temu (no uzhe bez detal'nyh chislennyh raschetov) predstavlena Coleman Miller'om. On takzhe podtverzhdaet, chto sliyaniya neitronnyh zvezd i chernyh dyr ne privodyat k poyavleniyu gamma-vspleska. astro-ph/0505010 Programma dlya kosmologicheskogo modelirovaniya GADGET-2 (The cosmological simulation code GADGET-2) Authors: Volker Springel Comments: submitted to MNRAS, 31 pages, 20 figures (reduced resolution), code available at http://www.mpa-garching.mpg.de/gadget Predstavleno detal'noe opisanie odnogo iz kosmologicheskih kodov. Sam kod dostupen. astro-ph/0505017 Novye ogranicheniya na modeli MOND po skopleniyam galaktik (New constraints on MOND from galaxy clusters) Authors: Etienne Pointecouteau, Joseph Silk Comments: 5 pages, 1 figure, MNRAS submitted Napomnim, chto MOND - Modified Newtonian Dynamics - schitaetsya al'ternativoi modeli temnoi materii. MOND v pervuyu ochered' prilagaetsya k krivym vrasheniya galaktik. Odnako est' i drugie nablyudatel'nye dannye, kotorye nado ob'yasnyat' (zametim, chto model' temnoi materii prekrasno s nimi spravlyaetsya). Avtory issleduyut ogranicheniya na model' MOND po dannym o skopleniyah galaktik. Pokazano, gde MOND vstrechaetsya s ser'eznymi trudnostyami. Eto skopleniya galaktik s ochen' goryachim gazom vnutri. Otmetim takzhe druguyu stat'yu s uchastiem Etienne Pointecouteau "Modeling the formation of galaxy clusters in MOND". V nei rech' idet o modelirovanii obrazovaniya skoplenii galaktik v scenariyah s modelyami MOND. Rezul'taty sravnenii s nablyudeniyami takzhe govoryat o problemah sootvetstvuyushei teorii. astro-ph/0505019 109 novyh galakticheskih rasseyannyh skoplenii (109 new Galactic open clusters) Authors: N.V. Kharchenko et al. Comments: Fig.2 and Fig.3 available as 1013_ASCC_13.jpg and ncomp.jpg, respectively. In fact, during this search of new clusters in the catalogue ASCC-2.5, we discovered 130 clusters. It turned out that 21 of them are listed in the online list DLAM as private communications. We stress the point that this paper is the first presentation of these 21 clusters in a refereed publication. Accepted for publication in A&A Privedeny dannye po sta s lishnim novym (t.e. tol'ko otkrytym) galakticheskim rasseyannym skopleniyam. Rezul'taty osnovany na obzore ASCC-2.5 (2.5 oznachaet 2.5 milliona zvezd). astro-ph/0505032 Evolyucionnyi status Be zvezd (The Evolutionary Status of Be Stars: Results from a Photometric Study of Southern Open Clusters) Authors: M. Virginia McSwain, Douglas R. Gies Comments: 44 pages, submitted to ApJS Be-zvezdy - eto massivnye (spektral'nyi klass V) zvezdy s emissionnymi liniyami. Linii voznikayut blagodarya istecheniyam s ekvatora zvezd. Istecheniya zhe poyavlyayutsya iz-za ochen' bystrogo vrasheniya. Prichiny etogo vrasheniya i rassmatrivayutsya v stat'e. Prichin bystrogo vrasheniya mozhet byt' tri: zvezdy rodilis' takimi zvezdy byli raskrucheny akkreciei v dvoinoi zvezdy raskrutilis' na odnom iz etapov svoei evolyucii na glavnoi posledovatel'nosti Avtory pokazyvayut, chto tert'ya prichina ne mozhet byt' sushestvennoi. Okolo 3/4 Be-zvezd raskrucheny v dvoinyh, a ostavshayasya chetvert' mozhet byt' svyazana s rozhdeniem bystrovrashayushihsya zvezd. obzor gr-qc/0504116 Nablyudatel'nye osnovy relyativistskoi gravitacii (Empirical Foundations of Relativistic Gravity) Authors: Wei-Tou Ni Comments: 18 pages; International Journal of Modern Physics D, in press (World Scientific, 2005); 100 Years of Gravity and Accelerated Frames--The Deepest Insights of Einstein and Yang-Mills (Ed.

Na nash vzglyad osobyi interes predstavlyaet chast', gde rech' idet o novyh dannyh, poluchennyh za poslednie neskol'ko let so sputnikov. Obsuzhdayutsya takzhe sputnikovye proekty, kotorye nachnut rabotu v samom blizhaishem budushem. obzor astro-ph/0505073 Sverhtekuchest', dinamika i precessiya neitronnyh zvezd (Neutron Star Superfluidity, Dynamics and Precession) Authors: M.

Yerli, C. Inam and S. Grebenev V pervuyu ochered' tekst posvyashen imenno precessii neitronnyh zvezd. Poskol'ku precessiya nablyudaetsya, my imeem vozmozhnost' poluchat' kosvennuyu informaciyu o vnutrennem stroenii neitronnyh zvezd po eshe odnomu kanalu. astro-ph/0505090 Nablyudeniya na VLT/UVES pokazyvayut otsutstvie variacii postoyannoi tonkogo vzaimodeistviya (VLT/UVES shows no cosmological variability of alpha) Authors: P. Molaro, M. Centurion, S. D'Odorico, S. Levshakov Comments: 3 pages, 1 postscript figure Dano kratkoe izlozhenie vazhnogo otricatel'nogo rezul'tata: dannye noveishih nablyudenii pokazyvayut, chto poka ne udalos' obnaruzhit' variacii postoyannoi tonkoi struktury po nablyudeniyam spektrov vnegalakticheskih ob'ektov. miniobzor astro-ph/0505156 Struinaya model' dlya rentgenovskih vspyshek (Jet Models of X-Ray Flashes) Authors: D.

Amati, S. Covino, and B. Gendre. Il Nuovo Cimento, in press My uzhe pisali o rabotah etih avtorov. Oni vhodyat v komandu HETE-2, a etot sputnik, krome obychnyh gamma-vspleskov, nablyudaet mnozhestvo t.n. rentgenovskih vspyshek (X-Ray Flashes). Eti vspyshki mogut byt' ne prosto "rodstvennikami" gamma-vspleskov, a pryamo-taki tem zhe samym yavleniem, no nablyudaemym nemnogo s drugoi tochki zreniya. Avtory dayut kratkii obzor nablyudatel'nyh dannyh po vspyshkam, ochen' korotko obsuzhdayut sushestvuyushie teorii. Osnovnaya chast' stat'i posvyashena sravneniyu dvuh modelei dzhetov. Pokazano, chto nablyudeniya v principe mogut vydelit' nailuchshuyu model'. My budem starat'sya hotya by perechislit' interesnye (dlya shirokoi publiki) stat'i, poyavivshiesya v razdele physics (vklyuchaya cross-listing). physics/0505027 Princip otnositel'nosti Uaitheda - neopublikovannaya lekciya J.
