Distant Echoes of the Milky Way’s Last Major Merger
The Astrophysical Journal, 2023 The majority of the Milky Way’s stellar halo consists of debris from our galaxy’s last major merger, the Gaia-Sausage-Enceladus (GSE). In the past few years, stars from the GSE have been kinematically and chemically studied in the inner 30 kpc of our ...

Types of Gaseous Envelopes of "Hot Jupiter" Exoplanets
, 2013 As a rule, the orbital velocities of "hot Jupiters," i.e., exoplanets with masses comparable to the mass of Jupiter and orbital semi-major axes less than 0.1 AU, are supersonic relative to the stellar wind, resulting in the formation of a bow shock.

Simulations of two-planet systems through all phases of stellar evolution: implications for the instability boundary and white dwarf pollution [PDF]
, 2013 Exoplanets have been observed at many stages of their host star's life, including the main sequence (MS), subgiant and red giant branch stages. Also, polluted white dwarfs (WDs) likely represent dynamically active systems at late times.

A new Monte Carlo code for star cluster simulations: II. Central black hole and stellar collisions [PDF]
, 2002 We have recently written a new code to simulate the long term evolution of spherical clusters of stars. It is based on the pioneering Monte Carlo scheme proposed by Henon in the 70's. Our code has been devised in the specific goal to treat dense galactic

Blue Stragglers After the Main Sequence [PDF]
, 2008 We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases.

The Astrophysical JournalWe use Athena++ to study the hydrodynamics of repeated star−accretion disk collisions close to supermassive black holes, and we discuss their implications for the origin of quasi-periodic eruptions (QPEs) and other repeating nuclear transients.

Mixing in massive stellar mergers [PDF]
, 2007 The early evolution of dense star clusters is possibly dominated by close interactions between stars, and physical collisions between stars may occur quite frequently.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

The Astrophysical JournalWhen binaries are injected into low-angular-momentum orbits around a central supermassive black hole (SMBH), various outcomes can occur, including binary tidal breakup, double stellar disruptions, and stellar collision.
