Super-Chandrasekhar white dwarfs by the evolution of magnetized main-sequence stars: New mass-limits from STARS simulation
Zenia Zuraiq, Banibrata Mukhopadhyay, Achal Kumar +4
We explore the time evolution of the magnetized main-sequence stars (MSs) to magnetized non-rotating white dwarfs (WDs) with a series of models, capturing modified Hertzsprung-Russ…
Brightest Cluster Galaxy ellipticity as proxy for halo shape: Orientation bias, assembly bias, and potential selection effects in SZ-selected clusters
Radhakrishnan Srinivasan, Tae-hyeon Shin, Anja von der Linden +93
The orientation of triaxial galaxy clusters with respect to the line-of-sight is expected to be one of the prime sources of scatter and potential bias in optical observables (e.g.,…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
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…
The Common Envelope Evolution Outcome. II. Short Orbital Period Hot Subdwarf B Binaries Reveal a Clear Picture
Hongwei Ge, Christopher A Tout, Ronald F Webbink +6
The common envelope evolution (CEE) is vital in forming short orbital period compact binaries. It covers many objects, such as double compact merging binaries, type Ia supernovae p…
Towards a holistic magnetic braking model from the evolution of cataclysmic variables to stellar spin-down -- I: the spin-down of fully convective M-dwarfs
Arnab Sarkar, Lev Yungelson, Christopher A. Tout
We extend a magnetic braking (MB) model, which has been used earlier to address the evolution of cataclysmic variables, to address the spin period evolution of fu…
