Asteroseismology of KIC 7107778: a binary comprising almost identical subgiants
Yaguang Li, Timothy R. Bedding, Tanda Li +5
We analyze an asteroseismic binary system: KIC 7107778, a non-eclipsing, unresolved target, with solar-like oscillations in both components. We used \emph{Kepler} short cadence tim…
The double helium-white dwarf channel for the formation of AM CVn binaries
Xianfei Zhang, Jinzhong Liu, C. Simon Jeffery +2
Most close double helium white dwarfs will merge within a Hubble time due to orbital decay by gravitational-wave radiation. However, a significant fraction with low mass ratios wil…
Evolution models of helium white dwarf--main-sequence star merger remnants: the mass distribution of single low-mass white dwarfs
Xianfei Zhang, Philip D. Hall, C. Simon Jeffery +1
It is not known how single white dwarfs with masses less than 0.5Msolar -- low-mass white dwarfs -- are formed. One way in which such a white dwarf might be formed is after the mer…
A note on periodicity of long-term variations of optical continuum in active galactic nuclei
Kai-Xing Lu, Yan-Rong Li, Shao-Lan Bi +1
Graham et al. found a sample of active galactic nuclei (AGNs) and quasars from the Catalina Real-time Transient Survey (CRTS) that have long-term periodic variations in optical con…
Modeling Eridani and asteroseismic tests of element diffusion
Ning Gai, Shao-Lan Bi, Yan-Ke Tang
Taking into account the helium and metal diffusion, we explore the possible evolutionary status and perform seismic analysis of MOST target: the star Eridani. We adopt the diff…
