An Episode of Occultation Events in Gaia21bcv
Klaus W. Hodapp, Eric Gaidos, Matthew A. Kenworthy +4
A previously unremarkable star near the Canis Major OB1/R1 association underwent an episode of multiple deep brightness minima. Light curves based on archival Gaia, ZTF, NEOWISE da…
Emerging Dimming as Coronal Heating Episodes
Anna V. Payne, Xudong Sun
Emerging dimming occurs in isolated solar active regions (ARs) during the early stages of magnetic flux emergence. Observed by the Atmospheric Imaging Assembly, it features a rapid…
The Outburst of the Young Star Gaia19bey
Klaus W. Hodapp, Larry Denneau, Michael Tucker +10
We report photometry and spectroscopy of the outburst of the young stellar object Gaia19bey. We have established the outburst light curve with archival Gaia G, ATLAS Orange, ZTF r-…
COol Companions ON Ultrawide orbiTS (COCONUTS). I. A High-Gravity T4 Benchmark around an Old White Dwarf and A Re-Examination of the Surface-Gravity Dependence of the L/T Transition
Zhoujian Zhang, Michael C. Liu, J. J. Hermes +7
We present the first discovery from the COol Companions ON Ultrawide orbiTS (COCONUTS) program, a large-scale survey for wide-orbit planetary and substellar companions. We have dis…
WISE J072003.20-084651.2B Is A Massive T Dwarf
Trent J. Dupuy, Michael C. Liu, William M. J. Best +21
We present individual dynamical masses for the nearby M9.5+T5.5 binary WISE J072003.20084651.2AB, a.k.a. Scholz's star. Combining high-precision CFHT/WIRCam photocenter astromet…
