Tertiary Tides with Eccentric Orbits
Yan Gao, Tjarda Boekholt, Devismita Panda +2
Within hierarchical triple stellar systems, there exists a tidal process unique to them, known as tertiary tides. In this process, the tidal deformation of a tertiary in a hierarch…
The Spatial Distribution of Type Ia Supernovae within Host Galaxies
Christopher Pritchet, Karun Thanjavur, Connor Bottrell +1
We study how type Ia supernovae (SNe Ia) are spatially distributed within their host galaxies, using data taken from the Sloan Digital Sky Survey (SDSS). This paper specifically te…
SCATTER: A New Common Envelope Formalism
Rosanne Di Stefano, Matthias U. Kruckow, Yan Gao +2
One of the most mysterious astrophysical states is the common envelope (CE) phase of binary evolution, in which two stars are enshrouded by the envelope shed by one of them. Intera…
Stellar Triples as a Source for Ba Stars
Yan Gao, Silvia Toonen, Nathan Leigh
Barium stars have been studied extensively over the past few decades, yet our current understanding of how these intriguing objects formed leaves much to be desired. Many trends ob…
A Catalogue of Potential Post Common Envelope Binaries
Matthias U. Kruckow, Patrick G. Neunteufel, Rosanne Di Stefano +2
We present a catalogue containing 839 candidate post common envelope systems. Common envelope evolution is very important in stellar astrophysics, particularly in the context of ve…
Three New Late-type Hypervelocity Star Candidates from Gaia DR2 with Refined Selection Criteria
Jiao Li, Shi Jia, Yan Gao +6
Several dozen hypervelocity star (HVS) candidates have been reported based on the second data release of Gaia (Gaia DR2). However, it has been proven that the radial velocities of…
An Empirical Fit for Viscoelastic Simulations of Tertiary Tides
Yan Gao, Silvia Toonen, Evgeni Grishin +2
Tertiary tides (TTs), or the continuous tidal distortion of the tertiary in a hierarchical triple system, can extract energy from the inner binary, inducing within it a proclivity…
High Velocity Runaway Binaries from Supernovae in Triple Systems
Yan Gao, Jiao Li, Shi Jia
Recent studies on hypervelocity stars (HVSs) have generated a need to understand the high velocity limits of binary systems. If runaway binary systems with high movement speeds wel…
Numerical Modelling of Tertiary Tides
Yan Gao, Alexandre C. M. Correia, Peter P. Eggleton +1
Stellar systems consisting of multiple stars tend to undergo tidal interactions when the separations between the stars are short. While tidal phenomena have been extensively studie…
SNe Ia as a cosmological probe
Xiangcun Meng, Yan Gao, Zhanwen Han
Type Ia supernovae luminosities can be corrected to render them useful as standard candles able to probe the expansion history of the universe. This technique was successful applie…
