Cataclysmic Variables and AM CVn Binaries in SRG/eROSITA + Gaia: Volume Limited Samples, X-ray Luminosity Functions, and Space Densities

Antonio C. Rodriguez, Kareem El-Badry, Valery Suleimanov +22

We present volume-limited samples of cataclysmic variables (CVs) and AM CVn binaries jointly selected from SRG/eROSITA eRASS1 and \textit{Gaia} DR3 using an X-ray + optical color-c…

The thermalization of -rays in radioactive expanding ejecta: A simple model and its application for Kilonovae and Ia SNe

Or Guttman, Ben Shenhar, Arnab Sarkar +1

A semi-analytic approximation is derived for the time-dependent fraction of the energy deposited by radioactive decay -rays in a homologously expanding plasma of genera…

Towards a holistic magnetic braking model -- II: explaining several long-term internal- and surface-spin properties of solar-like stars and the Sun

Arnab Sarkar, Patrick Eggenberger, Lev Yungelson +1

We extend our model of magnetic braking (MB), driven by an dynamo mechanism, from fully convective M-dwarfs (FCMDs) to explain the surface and internal spin …

One model to rule them all: magnetic braking from CVs to low-mass stars

Arnab Sarkar, Hongwei Ge, Lev Yungelson +1

We present the results of the study of cataclysmic variables (CVs) and AM Canum Venaticorum (AM CVn) stars with our double dynamo (DD) formalism of angular momentum loss (AML) by m…

Magnetic braking below the cataclysmic variable period gap and the observed dearth of period bouncers

Arnab Sarkar, Antonio C. Rodriguez, Sivan Ginzburg +2

Period bouncers are cataclysmic variables (CVs) that have evolved past their orbital period minimum. The strong disagreement between theory and observations of the relative fractio…
