Flaring Latitudes in Ensembles of Low Mass Stars
Ekaterina Ilin, Ruth Angus, Rodrigo Luger +2
The distribution of small-scale magnetic fields in stellar photospheres is an important ingredient in our understanding of the magnetism of low mass stars. Their spatial distributi…
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…
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…
A Relationship Between Stellar Age and Spot Coverage
Brett M. Morris
We investigate starspot distributions consistent with space-based photometry of F, G, and K stars in six stellar associations ranging in age from 10 Myr to 4 Gyr. We show that a si…
Temporal Evolution of Spatially-Resolved Individual Star Spots on a Planet-Hosting Solar-type Star: Kepler 17
Kosuke Namekata, James R. A. Davenport, Brett M. Morris +9
Star spot evolution is visible evidence of the emergence/decay of the magnetic field on stellar surface, and it is therefore important for the understanding of the underlying stell…
Stellar Properties of Active G and K Stars: Exploring the Connection Between Starspots and Chromospheric Activity
Brett M. Morris, Jason L. Curtis, Charli Sakari +2
We gathered high resolution spectra for an ensemble of 55 bright active and inactive stars using the ARC 3.5 m Telescope Echelle Spectrograph at Apache Point Observatory ($R\approx…
