We report that HD 110067, the recently announced host star of a resonant sextuplet of transiting sub-Neptunes, is not a single star as claimed in the discovery paper, but a wide hi…
Spectral analysis of ultra-cool white dwarfs polluted by planetary debris
Abbigail K. Elms, Pier-Emmanuel Tremblay, Boris T. Gänsicke +5
We identify two ultra-cool ( K) metal-polluted (DZ) white dwarfs WDJ21474035 and WDJ19220233 as the coolest and second coolest DZ stars known to date w…
Discovery of a uniquely cool and compact source at 28 parsecs from the Sun
Kevin Apps, R. L. Smart, Roberto Silvotti
We present the discovery of what appears to be both a uniquely cool and old white dwarf within 30 parsecs of the sun. DES J214756.46-403529.3 is detected in four separate surveys,…
Characterizing the Cool KOIs III. KOI-961: A Small Star with Large Proper Motion and Three Small Planets
Philip S. Muirhead, John Asher Johnson, Kevin Apps +21
We present the characterization of the star KOI 961, an M dwarf with transit signals indicative of three short-period exoplanets, originally discovered by the Kepler Mission. We pr…
Characterizing the Cool KOIs II. The M Dwarf KOI-254 and its Hot Jupiter
John Asher Johnson, J. Zachary Gazak, Kevin Apps +12
We report the confirmation and characterization of a transiting gas giant planet orbiting the M dwarf KOI-254 every 2.455239 days, which was originally discovered by the Kepler mis…
