The Nature of Classical Be Star Outbursts: A Multi-Epoch Study of the Be system EPIC 202060631
Qing Gao, Hailong Yuan
Through cross-matching the ASASSN photometric light curves and LAMOST spectroscopic observations, we serendipitously captured a rare major outburst event from the Be star EPIC 2020…
KIC 12268220: A Scuti Pulsating Star and an Active Protohelium White Dwarf in an Eclipsing Binary System
Kaiming Cui, Zhao Guo, Qing Gao +4
We present a photometric, spectroscopic, asteroseismic, and evolutionary analysis of the Algol-type eclipsing binary KIC 12268220. We find the O'Connell effect and anticorrelated e…
A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
Long rotation period main-sequence stars from Kepler SAP light curves
Kaiming Cui, Jifeng Liu, Shuhong Yang +7
Stellar rotation plays a key role in stellar activity. The rotation period could be detected through light curve variations caused by starspots. Kepler provides two types of light…
Do long-cadence data of {\it Kepler} satellite capture the basic properties of flares ?
Huiqin Yang, Jifeng Liu, Erlin Qiao +4
Flare research is becoming a burgeoning realm in the study of stellar activity due to the launch of {\it Kepler} in 2009. {\it Kepler} provides data with two time resolutions, i.e.…
Time-Variable Aluminum Absorption in the Polar AR Ursae Majoris, and an Updated Estimate for the Mass of the White Dwarf
Yu Bai, Stephen Justham, JiFeng Liu +3
We present spectra of the extreme polar AR Ursae Majoris (AR UMa) which display a clear Al I absorption doublet, alongside spectra taken less than a year earlier in which that feat…
