The influence of metallicity on stellar differential rotation and magnetic activity
Christoffer Karoff, Travis S. Metcalfe, Angela R. G. Santos +20
Observations of Sun-like stars over the last half-century have improved our understanding of how magnetic dynamos, like that responsible for the 11-year solar cycle, change with ro…
Chromospheric Activity of HAT-P-11: an Unusually Active Planet-Hosting K Star
Brett M. Morris, Suzanne L. Hawley, Leslie Hebb +6
Kepler photometry of the hot Neptune host star HAT-P-11 suggests that its spot latitude distribution is comparable to the Sun's near solar maximum. We search for evidence of an act…
The Multiplicity of M-Dwarfs in Young Moving Groups
Yutong Shan, Jennifer C. Yee, Brendan P. Bowler +11
We image 104 newly identified low-mass (mostly M-dwarf) pre-main sequence members of nearby young moving groups with Magellan Adaptive Optics (MagAO) and identify 27 binaries with…
Long Term Photometric Variability in Kepler Full Frame Images: Magnetic Cycles of Sun-Like Stars
Benjamin T. Montet, Guadalupe Tovar, Daniel Foreman-Mackey
Photometry from the Kepler mission is optimized to detect small, short duration signals like planet transits at the expense of long-term trends. This long-term variability can be r…
