RotNet: Fast and Scalable Estimation of Stellar Rotation Periods Using Convolutional Neural Networks
J. Emmanuel Johnson, Sairam Sundaresan, Tansu Daylan +6
Magnetic activity in stars manifests as dark spots on their surfaces that modulate the brightness observed by telescopes. These light curves contain important information on stella…
Refining the transit timing and photometric analysis of TRAPPIST-1: Masses, radii, densities, dynamics, and ephemerides
Eric Agol, Caroline Dorn, Simon L. Grimm +32
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST and K2 transit time measurements, and…
The hot dayside and asymmetric transit of WASP-189b seen by CHEOPS
M. Lendl, Sz. Csizmadia, A. Deline +102
The CHEOPS space mission dedicated to exoplanet follow-up was launched in December 2019, equipped with the capacity to perform photometric measurements at the 20 ppm level. As CHEO…
A Giant Planet Candidate Transiting a White Dwarf
Andrew Vanderburg, Saul A. Rappaport, Siyi Xu +61
Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During…
A super-Earth and a sub-Neptune orbiting the bright, quiet M3 dwarf TOI-1266
B. -O. Demory, F. J. Pozuelos, Y. Gomez Maqueo Chew +70
We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting the bright (), quiet, and nearby (37 pc) M3V dwarf TOI-1266. We validate the plane…
Short Term Variability of Evolved Massive Stars with TESS II: A New Class of Cool, Pulsating Supergiants
Trevor Z. Dorn-Wallenstein, Emily M. Levesque, Kathryn F. Neugent +3
Massive stars briefly pass through the yellow supergiant (YSG) phase as they evolve redward across the HR diagram and expand into red supergiants (RSGs). Higher-mass stars pass thr…
