В данной работе с помощью одномерной самосогласованной аэрономической модели были получены высотные профили температуры, скорости и плотности для горячего нептуна GJ 436b. Мы проследили расширение газовой оболочки под действием нагрева от жесткого излучения родительской звезды тонкого атмосферного слоя 1.02R 0 до 5R . Используемая модель учитывает вклад надтепловых частиц, что значительно уточняет функцию атмосферы. Установлено, формируется структура атмосферы двумя характерными шкалами...
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 127 SU UMa-type dwarf novae observed mainly during 2016--2017 season and characterized these objects. We provide updated statistics relation between orbital period variation superhumps, variations rebrightening type in WZ Sge-type obtained minimum 0.05290(2)d confirmed presence gap above ~0.09d. note that four objects (NY Her, 1RXS J161659.5+620014, CRTS J033349.8-282244 SDSS...
V616 Mon = A0620-00 is a prototype of black hole transient X-ray binaries. Our 2003-16 optical photometry the object during quiescence, obtained by 50-250 cm telescopes in Crimea, Caucasus Mountains and Slovakia, consists ~ 7660 CCD frames Johnson-Cousins $V,R,R_C,I$ bands integral light. During 2003, 2008-9 2015-16 passive states, phase light curve binary exhibited mainly variations caused an ellipsoidal shape red dwarf component. 2004-6 2009-14 active states significant aperiodic...
Abstract We observed the first-ever recorded outburst of PM J03338+3320, cataclysmic variable selected by proper-motion survey. The was composed a precursor and main superoutburst. occurred at least 5 d before maximum Despite this separation, long-period superhumps were continuously seen between period these is longer than its orbital 6.0(1)% can be interpreted to reflect dynamical precession rate 3 : 1 resonance for mass ratio 0.172(4). These smoothly evolved into those in observations...

Abstract In this work we applied the previously developed self-consistent 1D model of hydrogen-helium atmosphere with suprathermal electrons to close-in hot neptune GJ 436 b. The obtained height profile density shows two-scale structure planetary atmosphere. mass-loss rate is found be about .
In this work we present the results of modeling exoplanet pi Men c upper atmosphere, produced using previously developed one-dimensional self-consistent aeronomic model. The model used takes into account contribution suprathermal particles, which significantly refines heating function atmosphere. hight profiles temperature, velocity and density were obtained, atmospheric mass-loss rate was calculated. presence two hight-scales in structure atmosphere found: first corresponds to a relatively...
