Infrared spectroscopy of the recent outburst in V1047 Cen (Nova Centauri 2005)
T. R. Geballe, D. P. K. Banerjee, A. Evans +14
Fourteen years after its eruption as a classical nova (CN), V1047 Cen (Nova Cen 2005) began an unusual re-brightening in 2019 April. The amplitude of the brightening suggests that…
TOI-216b and TOI-216c: Two warm, large exoplanets in or slightly wide of the 2:1 orbital resonance
Rebekah I. Dawson, Chelsea X. Huang, Jack J. Lissauer +32
Warm, large exoplanets with 10-100 day orbital periods pose a major challenge to our understanding of how planetary systems form and evolve. Although high eccentricity tidal migrat…
The Rise and Fall of the King: The Correlation between FO Aquarii's Low States and the White Dwarf's Spindown
Colin Littlefield, Peter Garnavich, Mark R. Kennedy +45
The intermediate polar FO Aquarii (FO Aqr) experienced its first-reported low-accretion states in 2016, 2017, and 2018, and using newly available photographic plates, we identify p…
A super-Earth and two sub-Neptunes transiting the nearby and quiet M dwarf TOI-270
Maximilian N. Günther, Francisco J. Pozuelos, Jason A. Dittmann +57
We report the Transiting Exoplanet Survey Satellite discovery of three small planets transiting one of the nearest and brightest M dwarf hosts to date, TOI-270 (TIC 259377017; K-ma…
Fast-Cadence TESS Photometry and Doppler Tomography of the Asynchronous Polar CD Ind: A Revised Accretion Geometry from Newly Proposed Spin and Orbital Periods
Colin Littlefield, Peter Garnavich, Koji Mukai +5
The TESS spacecraft observed the asynchronous polar CD Ind at a two-minute cadence almost continuously for 28 days in 2018, covering parts of 5 consecutive cycles of the system's 7…
NSV 1440: First WZ Sge-type Object in AM CVn stars and candidates
Keisuke Isogai, Taichi Kato, Berto Monard +5
In 2015 and 2017, the AM CVn candidate NSV 1440 showed superoutbursts having the characteristic features of WZ Sge-type dwarf novae (DNe). By analogy with hydrogen-rich cataclysmic…
The PDS 110 observing campaign - photometric and spectroscopic observations reveal eclipses are aperiodic
Hugh P. Osborn, Matthew Kenworthy, Joseph E. Rodriguez +71
PDS 110 is a young disk-hosting star in the Orion OB1A association. Two dimming events of similar depth and duration were seen in 2008 (WASP) and 2011 (KELT), consistent with an ob…
