Na moi vzglyad ochen' pokazatel'naya stat'ya. V korotkoe zametke avtory predstavlyayut prostoi analiticheskii rezul'tat, kotoryi tem ne menee imeet sushestvennye astrofizicheskie prilozheniya v oblasti, gde slozhnye chislennye modeli kazalos' by davno i prochno zahvatili vlast' v svoi cifrovye ruki.
Pokazano, chto odnorodno vrashayushayasya barotropnaya zhidkost' vo vneshnem potenciale dostigaet istinnogo minimuma energii tol'ko esli profil' vrasheniya vezde yavlyaetsya dozvukovym. Vazhnym sledstviem dlya astrofiziki yavlyaetsya to, chto evolyuciya sistemy (k odnorodnomu vrasheniyu ili k sisteme yadro-disk) zavisit ot harakteristiki profilya vrasheniya. Eto mozhet imet' znachenie dlya issledovaniya yader molekulyarnyh oblakov.

Seichas izuchenie relyativistskih udarnyh voln stanovitsya ochen' aktual'noi oblast'yu v svyazi s vozmozhnym primeneniem k gamma-vspleskam. V stat'e avtory issledovayut tolshinu udarnoi volny dlya raznogo uravneniya sostoyaniya gaza v relyativistskom sluchae i sravnivayut rezul'taty s nerelyativistskim.

Na samom dele rech' tut poidet srazu o chetyreh stat'yah (pocheum-to chasto stat'i po blizkim temam nezavisimo poyavlyayutsya v odnom vypuske astro-ph).
Gomez i Cox v svoei rabote predstavlyayut rezul'taty trehmernogo modelirovaniya gazovoi struktury Galaktiki. Vazhen uchet spiral'noi struktury (v svyazi s etim avtory predstavlyayut vtoruyu stat'yu astro-ph/0207635, posvyashennuyu analiticheskoi approsimacii gravitacionnogo potenciala rukava Galaktiki).
Krome etih rabot poyavilas' stat'ya po turbulentnosti v galakticheskih diskah (Wada et al. astro-ph/0207641). Zdes' avtory provodyat dvumernye raschety s uchetom samogravitacii veshestva mezhzvezdnoi sredy.
Nu i nakonec rabota Mir Abbas Jalali i Mehdi Abolghasemi (astro-ph/0207644) posvyashena analiticheskim issledovaniyam gazovyh diskov.
Rezul'taty, poluchennye v pervyh dvuh rabotah, primenyayutsya v osnovnom k nashei Galaktike, v tret'ei - k NGC 2915, a v poslednei - k Bol'shomu Magellanovu Oblaku.

Avtory rassmatrivayut ustoichivost' zamagnichennoi sredy, sostoyashei iz potoka neitral'nyh i potoka zaryazhennyh chastic. Rezul'taty primenyayutsya k zvezdam pozdnih spektral'nyh klassov s sil'nymi vetrami (v takih ob'ektah sushestvuyut SiO mazery).

Dlya lyubitelei polemiki. Stat'ya yavlyaetsya korotkim kommentariem na rabotu astro-ph/0207561, o kotoroi ya tozhe pisal. Sut' kommentariya ochen' prosta: vyvody v astro-ph/0207561 neverny.

Avtory chislenno issleduyut zatuhanie vysokoskorostnyh turbulentnyh techenii v plotnyh molekulyarnyh oblakah. Poskol'ku rech' idet ob otnositel'no vysokih plotnostyah, avtory uchityvayut himicheskie processy dlya vodoroda, ugleroda i kisloroda. Rezul'taty sravnivayutsya s bolee rannimi raschetami.

Daetsya obzor po nablyudatel'nym proyavleniyam kosmicheskih magnitnyh polei. Osoboe vnimanie udelyaetsya polyu Galaktiki, a takzhe vnegalakticheskim ob'ektam. Izlagayutsya osnovy nablyudatel'nyh metodov (polyarizaciya sveta zvezd, effekt Zeemana, mera vrasheniya i dr.).
O mezhgalakticheskii magnitnyh polyah sm. takzhe astro-ph/0209091. A o modelirovanii mezhgalakticheskoi sredy - astro-ph/0209094.

Kak formiruetsya nachal'naya funkciya mass zvezd? Po vsei vidimosti ona neposredstvennym obrazom svyazana so svoistvami turbulentnosti v mezhzvezdnoi srede. Avtory rassmatrivayut vsyu cepochku: ot parametrov turbulentnosti do parametrov zvezd.

Po mneniyu avtorov v poslednie godu byl dostignut znachitel'nyi progress v ponimanii svoistv MGD turbulentnosti. Avtory dayut obzor etih dostizhenii i obsuzhdayut nekotorye astrofizicheskie prilozheniya.

Uravnenie Greda-Shafranova (Grad-Shafranov) pozvolyayut reshat' ochen' mnogie stacionarye osesimmetrichnye zadachi. Odno iz polei ih prilozhenii - gidrodinamika, v tom chisle i v ramkah obshei teorii otnositel'nosti, t.e. vblizi kompaktnyh zvezd i chernyh dyr.

Ochen' special'naya stat'ya, i tem ne menee... Issledovanie udarnyh voln v magnitogidrodinamike s uchetom effektov OTO - eto "grob s muzykoi". Zadacha bezumno slozhnaya, a reshat' ee nado (est' massa ochen' vazhnyh i interesnyh astrofizicheskih prilozhenii). Tak chto "bezumstvu hrabryh poem my pesnyu..."
