No Such Thing as a Simple Flare: Substructure and QPPs Observed in a Statistical Sample of 20 Second Cadence TESS Flares
Ward S. Howard, Meredith A. MacGregor
A 20 second cadence TESS monitoring campaign of 226 low-mass flare stars during Cycle 3 recorded 3792 stellar flares of >10^32 erg. We explore the time-resolved emission and substr…
EvryFlare IV: Detection of periodicity in flare occurrence from cool stars with TESS
Ward S. Howard, Nicholas M. Law
Phased flaring, or the periodic occurrence of stellar flares, may probe electromagnetic star-planet interaction (SPI), binary interaction, or magnetic conditions in spots. For the…
Low-Cost Access to the Deep, High-Cadence Sky: the Argus Optical Array
Nicholas M. Law, Hank Corbett, Nathan W. Galliher +16
New mass-produced, wide-field, small-aperture telescopes have the potential to revolutionize ground-based astronomy by greatly reducing the cost of collecting area. In this paper,…
Rotation periods of TESS Objects of Interest from the Magellan-TESS Survey with multiband photometry from Evryscope and TESS
Ward S. Howard, Johanna Teske, Hank Corbett +8
Stellar RV jitter due to surface activity may bias the RV semi-amplitude and mass of rocky planets. The amplitude of the jitter may be estimated from the uncertainty in the rotatio…
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 Extremely Short Duration Flare from Proxima Centauri Using Millimeter through FUV Observations
Meredith A. MacGregor, Alycia J. Weinberger, R. O. Parke Loyd +17
We present the discovery of an extreme flaring event from Proxima Cen by ASKAP, ALMA, HST, TESS, and the du Pont Telescope that occurred on 2019 May 1. In the millimeter and FUV, t…
