Authors: Lior Shamir, Robert J. Nemiroff Comments: 21 pages, 7 figures, 3 tables, accepted PASP Kak izvestno, nauka ne zanimaetsya chudesami, t.e. nevosproizvodimymi yavleniyami. V astronomii v takuyu kategriyu mogut popadat' ochen' bystrye sobytiya, kotorye ne uspevayut kak sleduet rassmotret'. Odnako uchenye delayut vse, chto v ih silah, chtoby reshit' etu problemu. Sredi vozmozhnyh "chudes" mogut byt' ochen' bystrye tranzienty, dazhe v opticheskom diapazone. Poiskom takih sobytii zanimayutsya s pomosh'yu ochen' shirokougol'nyh kamer. 20 aprelya etogo goda dve kamery (odna v Chili, drugaya - v Ispanii) zaregistrirovali yarkuyu (5-ya velichina) vspyshku dlitel'nost'yu okolo 10 minut. Pervichnyi analiz pokazal, chto sobytie dolzhno byt' svyazano s astronomicheskim ob'ektom. Odnako pozzhe okazalos', chto sobytie ne bylo zaregistrirovano tret'ei kameroi. V dannoi stat'e avtory tshatel'no obsuzhdayut eto konkretnoe sobytie, a takzhe rassuzhdayut o tom, kak pravil'no iskat' podlinnye opticheskie tranzienty. Samo nablyudavsheesya sobytie avtory svyazyvayut s blikom ot kakogo-to kosmicheskogo musora.
Authors: Roberto Trotta, Richard Bower Comments: 9 pages, no figures. Review article to appear in "Astronomy and Geophyiscs" Hotya Monti Paiton v lice Braiana i prizyvali nas smotret' na svetluyu storonu zhizni, tem ne menee nado pomnit' i o temnoi storone... Odnako ne stoit toropit'sya delat' mrachnoe lico, v dannom sluchae rech' idet vsego lish' ob issledovanii temnoi energii. Avtory dayut detal'nyi obzor tipov nablyudenii, kotorye mogut dat' kakuyu-to vazhnuyu informaciyu o svoistvah etogo komponenta vselennoi. Takzhe rassmatrivayutsya konkretnye proekty, kotorye v blizhaishee vremya dolzhny prolit' svet na temnuyu storonu. See you on the dark side of the Moon. And there is no dark side of the Moon really.
Authors: A. M. Hillas Comments: 11 pages, 8 figures, Based on invited talk in "Cosmology, Galaxy Formation and Astroparticle Physics on the pathway to the SKA", Oxford, April 2006 Ochen' emkii i udachnyi obzor po kosmicheskim lucham. Vsyacheski rekomenduetsya dlya oznakomleniya s sovremennym sostoyaniem del.
Authors: David Polishook, Noah Brosch Comments: 5 pages, 2 figures, invited paper for NASA's "Near-Earth Object Detection, Characterization, and Threat Mitigation" workhop, Colorado, June 2006 NEAs - Near Earth Asteroids. Stat'ya posvyashena ocenke doli dvoinyh ob'ektov sredi nih. Dolya okazyvaetsya velika. Esli v pervyh stat'yah rech' shla lish' o 15 procentah, potom o 50, to seichas avtory pishut o 2/3. Hotya zamechu, chto vyvody avtorov osnovyvayutsya na nebol'shom chisle izuchennyh ob'ektov, chto, na moi vzglyad, delaet prezhdevremennymi vyvody o tochnoi doli dvoinyh asteroidov, prohodyashih vblizi Zemli.
Authors: A. De Luca, P.A. Caraveo, S. Mereghetti, A. Tiengo, G.F. Bignami Comments: Accepted for publication in Science. Published online via Science Express on 2006, July 6. 17 pages, 7 figures Kompaktnyi istochnik v ostatke sverhnovoi RCW 103 izvesten uzhe dostatochno davno. Tak zhe davno bylo yasno, chto on ne pohozh na "normal'nuyu" moloduyu neitronnuyu zvezdu. Vyskazyvalis' samye raznye gipotezy. Peremennost' istochnika, v svoyu ochered', tozhe ne yavlyaetsya novost'yu. I dazhe periodichnost' peremennosti uzhe obsuzhdalas', naprimer v rabotah G.G.Pavlova i ego kolleg. I vse-taki vot on - gvozd': detal'nye nablyudeniya na HMM-N'yutone pokazali nalichie chetkoi periodichnosti s periodom 6.67 chasa. Priroda istochnika po-prezhnemu ostaetsya neponyatnoi. To li eto dvoinaya sistema s malomassivnym kompan'onom (prisutstvie kompan'ona nikak v drugih diapazonah ne proyavlyaetsya), to li eto odinochnaya neitronnaya zvezda s anomal'no bol'shim (dlya takogo molodogo ob'ekta) periodom vrasheniya, to li chto-to eshe. Ne mogu ne vspomnit' svoyu staruyu ideyu o tom, chto istochnik yavlyaetsya "staroi" neitronnoi zvezdoi, a sam ostatok porozhden vzryvom kompan'ona po dvoinoi sisteme. Teper' zhe "staraya" neitronnaya zvezda akkreciruet vybroshennoe veshestvo. Pravda, period v chetvert' dnya tut takzhe ploho podhodit (pri takom periode orbital'naya skorost' slishkom velika, chtoby ozhidat' znachimoi akkrecii iz sredy vokrug). Mozhno postroit' model' v duhe "epiciklov", skazav, chto iznachal'no imelas' troinaya sistema (dve massivnye zvezdy i odna malomassivnaya). Massivnaya zvezda, vzrvavshayasya vtoroi, porodila nablyudaemyi ostatok, a pervaya porodila akkreciruyushuyu neitronnuyu zvezdu. Kak by to ni bylo, polagayu, chto ne stoit sbrasyvat' so schetov vozmozhnost', chto v kachestve rentgenovskogo istochnika my vidim ne tu zhe neitronnuyu zvezdu, chto porodila ostatok. Budem dumat' i zhdat'.
Authors: Jeremy G. Wertheimer, Gregory Laughlin Comments: 10 pages total, 4 pages of text, 1 page of references, 3 figures, and 2 tables This article will be published in The Astronomical Journal Okazyvaetsya, chto vopros etot ne tol'ko do sih por ne reshen, no dlya ego razresheniya nuzhny novye bolee tochnye nablyudeniya! Delo v tom, chto Proksima slishkom daleka ot pary zvezd, sostavlyayushih Al'fu Centavra. Rasstoyanie kak raz poryadka togo, na kotorom prilivnoe deistvie Galaktiki mozhet razrushit' sistemu. Veroyatno, chto Proksima seichas nahoditsya v apoastre svoei orbity, no mozhet byt', chto vse-taki tri zvezdy ne obrazuyut edinuyu sistemu. Tak chto bez novyh nablyudenii ne oboitis'.
Authors: Michael S. Kelley et al. Comments: Accepted for publication in the Astrophysical Journal 48 pages, 15 figures, 10 tables Hotya kosmicheskii infrakrasnyi teleskop imeni Spitcera byl sozdan v pervuyu ochered' dlya izucheniya zvezdoobrazovaniya i kosmologicheskih issledovanii, ego primenyayut i dlya nablyudenii ob'ektov Solnechnoi sistemy, naprimer komet. V stat'e privodyatsya dannye nablyudenii treh komet, dostatochno blizkih k Solncu (i Zemle) na moment nablyudeniya. Nikakih superkrasivyh kartinok net, zato est' dannye po chasticam v golovah komet i po ih yadram.
Authors: Inseok Song et al. Comments: 18 pages, 3 figures, 3 tables. Accepted in ApJ Pod nomerom vosem' v proshlogodnii spisok samyh vazhnyh astronomicheskih otkrytii (po publikaciyam v Arhive) ya vnes obnaruzhenie planetnogo sputnika u burogo karlika. Sushestvennym momentom yavlyaetsya to, chto udalos' poluchit' pryamoe izobrazhenie planety (ob etom takzhe mozhno prochest' v iyul'skom nomere "Vokrug Sveta"). Pervoe izobrazhenie bylo polucheno eshe v 2004 g., no tol'ko v 2005 byli polucheny podtverzhdeniya togo |
