More Rapidly Rotating PMS M Dwarfs with Light Curves Suggestive of Orbiting Clouds of Material
John Stauffer, Luisa Rebull, Trevor David +8
In a previous paper, using data from K2 Campaign 2, we identified 11 very low mass members of the Oph and Upper Scorpius star-forming region as having periodic photometric vari…
Prominence formation and ejection in cool stars
Carolina Villarreal D'Angelo, Moira Jardine, Victor See
The observational signatures of prominences have been detected in single and binary G and K type stars for many years now, but recently this has been extended to the M dwarf regime…
The open flux evolution of a solar-mass star on the main sequence
V. See, M. Jardine, A. A. Vidotto +9
Magnetic activity is known to be correlated to the rotation period for moderately active main sequence solar-like stars. In turn, the stellar rotation period evolves as a result of…
Radio Exploration of Planetary Habitability: Conference Summary
T. Joseph W. Lazio, A. Wolszczan, M. Güdel +4
Radio Exploration of Planetary Habitability was the fifth in the series of American Astronomical Society's Topical Conference Series. Notable aspects of the conference included the…
MOVES I. The evolving magnetic field of the planet-hosting star HD189733
R. Fares, V. Bourrier, A. A. Vidotto +9
HD189733 is an active K dwarf that is, with its transiting hot Jupiter, among the most studied exoplanetary systems. In this first paper of the Multiwavelength Observations of an e…
Studying stellar spin-down with Zeeman-Doppler magnetograms
V. See, M. Jardine, A. A. Vidotto +11
Magnetic activity and rotation are known to be intimately linked for low-mass stars. Understanding rotation evolution over the stellar lifetime is therefore an important goal withi…
Orbiting Clouds of Material at the Keplerian Co-Rotation Radius of Rapidly Rotating Low Mass WTTs in Upper Sco
John Stauffer, Andrew Collier Cameron, Moira Jardine +8
Using K2 data, we have identified 23 very low mass members of the Oph and Upper Scorpius star-forming region as having periodic photometric variability not easily explained by…
