The Extremely Metal-Poor SN 2023ufx: A Local Analog to High-Redshift Type II Supernovae
Michael A. Tucker, Jason Hinkle, Charlotte R. Angus +26
We present extensive observations of the Type II supernova (SN II) 2023ufx which is likely the most metal-poor SN II observed to-date. It exploded in the outskirts of a low-metalli…
A JWST Medium Resolution MIRI Spectrum and Models of the Type Ia supernova 2021aefx at +415 d
C. Ashall, P. Hoeflich, E. Baron +39
We present a JWST MIRI/MRS spectrum (5-27 m) of the Type Ia supernova (SN Ia), SN 2021aefx at days past -band maximum. The spectrum, which was obtained during t…
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…
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…
