The Stellar Activity of TRAPPIST-1 and Consequences for the Planetary Atmospheres
Rachael M. Roettenbacher, Stephen R. Kane
The signatures of planets hosted by M dwarfs are more readily detected with transit photometry and radial velocity methods than those of planets around larger stars. Recently, tran…
Contemporaneous Imaging Comparisons of the Spotted Giant Geminorum Using Interferometric, Spectroscopic, and Photometric Data
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +8
Nearby, active stars with relatively rapid rotation and large starspot structures offer the opportunity to compare interferometric, spectroscopic, and photometric imaging technique…
No Sun-like dynamo on the active star Andromedae from starspot asymmetry
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +12
Sunspots are cool areas caused by strong surface magnetic fields inhibiting convection. Moreover, strong magnetic fields can alter the average atmospheric structure, degrading our…
