A Systematic Gaia--ZTF Search for Short-Period Blue Compact-Binary Candidates
Jiamao Lin, Liangliang Ren, Yilong Li +7
We present a catalog of 147 short-period (10.34--106.46~min) blue compact-binary candidates, identified by combining Gaia DR3 astrometry and photometry with ZTF DR23 light curves v…
Sub-Neptunes Show a Stronger Correlation with Cold Jupiters than Super-Earths Especially in Metal-rich Systems
Di-Chang Chen, Fei Dai, Bo Ma +2
Correlations between the inner small planets and cold giants encodes the formation and evolution of planetary systems. It remains unclear if the correlation differs on the two side…
Fates of the sub-stellar objects (FOSSO) II. Evidence for Suppression of Metal Pollution in White Dwarfs by Close Substellar Companions
Zhangliang Chen, Xin-Yue Zhang, Di-Chang Chen +4
Approximately 25--50\% of white dwarfs (WDs) exhibit metal absorption lines in their photospheres, interpreted as evidence of ongoing/recent accretion of planetary debris from remn…
Inversion of Hydrogen-rich Atmosphere and Water Content for GJ 486b
Junda Zhou, Zhenyang Huang, Di-Chang Chen +1
GJ~486b is a close-in planet orbiting an M dwarf and is therefore expected to have undergone strong atmospheric escape. Motivated by theoretical and observational studies on the co…
How a Close-in Planet Protects its White Dwarf Host from Pollution
Xin-Yue Zhang, Ji-Wei Xie, Di-Chang Chen +1
Approximately 25-50% of white dwarfs (WDs) exhibit metal absorption lines in their photospheres, which are attributed to accretion from their remnant planetary systems. Although wh…
