Angular Momentum Loss during Stable Mass Transfer onto a Compact Object: The Effect of Mass Loss via Accretion Disk Winds

The Astrophysical Journal
We use an analytic framework to calculate the evolution of binary orbits under a physically motivated model that accounts for angular momentum loss associated with winds from an accretion disk around the compact-objected accretor.

Stellar-Dynamics of Young Star Clusters [PDF]

arXiv, 2000
The stellar-dynamical evolution of bound star clusters during the first few Myr is dominated by binary-binary and binary-star interactions, the rapid sinking of the most massive stars to the centre of the clusters and mass loss from evolving stars. The consequences of these processes for the binary and stellar population in clusters, and for the star ...

Effects of dark matter on the spontaneous scalarization in neutron stars

European Physical Journal C: Particles and Fields
Dark matter, an important portion of compact objects, can influence different phenomena in neutron stars. The spontaneous scalarization in the scalar-tensor gravity has been proposed for neutron stars.

Rethinking Thorne–Żytkow Object Formation: The Fate of X-Ray Binary LMC X-4 and Implications for Ultra-long Gamma-Ray Bursts

The Astrophysical Journal
We present a start-to-end simulation aimed at studying the long-term fate of high-mass X-ray binaries and whether a Thorne–Żytkow object (TŻO) might ultimately be assembled.

The HST Nondetection of SN Ia 2011fe 11.5 yr after Explosion Further Restricts Single-degenerate Progenitor Systems

The Astrophysical Journal
We present deep Hubble Space Telescope imaging of the nearby Type Ia supernova (SN Ia) 2011fe obtained 11.5 yr after explosion. No emission is detected at the SN location to a 1 σ (3 σ ) limit of F555W > 30.2 (29.0) mag, or equivalently M _V > 1.2 (−0.1)

Transient Processes in a Binary System with a White Dwarf

Acta Polytechnica CTU Proceedings, 2015
Using the results of 3D gas dynamic numerical simulations we propose a mechanism that can explain the quiescent multihumped shape of light curves of WZ Sge short-period cataclysmic variable stars.

Gamma-ray binaries : a bridge between Be stars and high energy astrophysics [PDF]

arXiv, 2014
Advances in X-ray and gamma-ray astronomy have opened a new window on our universe and revealed a wide variety of binaries composed of a compact object and a Be star. In Be X-ray binaries, a neutron star accretes the Be disk and truncates it through tidal interactions. Such systems have important X-ray outbursts, some related to the disk structure.

Runaway OB Stars in the Small Magellanic Cloud. III. Updated Kinematics and Insights into Dynamical versus Supernova Ejections

The Astrophysical Journal
We use the kinematics of field OB stars to estimate the frequencies of runaway stars generated by the dynamical ejection scenario (DES), the binary supernova scenario (BSS), and the combined two-step mechanism.
