Stripped helium stars in UV
L. R. Yungelson, A. G. Kuranov, A. V. Mishakina
The model of Galactic population of stripped helium stars, the remnants of primary components of close binaries after RLOF is presented. These st…
Looking for Signs of Unresolved Binarity in the Continuum of LAMOST Stellar Spectra
Mikhail Prokhorov, Kefeng Tan, Nikolay Samus +10
We describe an attempt to derive the binarity rate of samples of 166 A-, F-, G-, and K-type stars from LAMOST DR5 and 1000 randomly selected presumably single stars from Gaia DR3 c…
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…
Elusive hot stripped helium stars in the Galaxy I. Evolutionary stellar models in the gap between subdwarfs and Wolf-Rayet stars
L. Yungelson, A. Kuranov, K. Postnov +3
Stellar evolution theory predicts the existence of He-core remnants of the primary components of intermediate-mass close binaries that lost most of their H/He envelopes due to the…
