HD 5501: A Rapidly Evolving Interacting Eclipsing Binary with a Variable Light Curve and H Emission
Richard O. Gray, Christopher. J. Corbally, Sean Curry +19
HD~5501, a hitherto little studied eclipsing binary with an early A-type primary, has been caught in a short-lived, astrophysically interesting phase of its binary evolution. Recen…
TU Tau B: The Peculiar 'Eclipse' of a possible proto-Barium Giant
Richard O. Gray, Christopher J. Corbally, Michael M. Briley +26
TU Tau (= HD 38218 = HIP 27135) is a binary system consisting of a C-N carbon star primary and an A-type secondary. We report on new photometry and spectroscopy which tracked the r…
Combined Spectroscopic and Photometric Analysis of Flares in the Dwarf M Star EV Lacertae
David Boyd, Robert Buchheim, Sean Curry +6
We report results of an observing campaign to study the dwarf M flare star EV Lacertae. Between October 2021 and January 2022 we obtained concurrent B band photometry and low resol…
TIC 172900988: A Transiting Circumbinary Planet Detected in One Sector of TESS Data
Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz +86
We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star…
Discovery of an intermediate-luminosity red transient in M51 and its likely dust-obscured, infrared-variable progenitor
Jacob E. Jencson, Scott M. Adams, Howard E. Bond +49
We present the discovery of an optical transient (OT) in Messier 51, designated M51 OT2019-1 (also ZTF19aadyppr, AT 2019abn, ATLAS19bzl), by the Zwicky Transient Facility (ZTF). Th…
Modern observations of Hubble's first-discovered Cepheid in M31
M. Templeton, A. Henden, W. Goff +9
We present a modern ephemeris and modern light curve of the first-discovered Cepheid variable in M31, Edwin Hubble's M31-V1. Observers of the American Association of Variable Star…
