Gaia0007-1605: an old triple system with an inner brown dwarf-white dwarf binary and an outer white dwarf companion
Alberto Rebassa-Mansergas, Siyi Xu, Roberto Raddi +5
We identify Gaia0007-1605AC as the first inner brown dwarf-white dwarf binary of a hierarchical triple system in which the outer component is another white dwarf (Gaia0007-1605B).…
Infrared Excesses around Bright White Dwarfs from Gaia and unWISE. II
Samuel Lai, Erik Dennihy, Siyi Xu +7
Infrared excesses around white dwarf stars indicate the presence of various astrophysical objects of interest, including companions and debris disks. In this second paper of a seri…
Five New Post-Main-Sequence Debris Disks with Gaseous Emission
Erik Dennihy, Siyi Xu, Samuel Lai +13
Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The mo…
Exocomets from a Solar System Perspective
Paul A. Strøm, Dennis Bodewits, Matthew M. Knight +24
Exocomets are small bodies releasing gas and dust which orbit stars other than the Sun. Their existence was first inferred from the detection of variable absorption features in ste…
