Intense but Harmless: Exo-Space Weather Around an M Dwarf with a Single-Hemisphere Dynamo
Zheng Sun, Julián D. Alvarado-Gómez, Hui Tian +4
M dwarfs are among the most promising host stars in the search for habitable exoplanets. However, their active atmospheres drive intense magnetic activity, including energetic flar…
Hubble reveals complex multi-scale structure in the edge-on protoplanetary disk IRAS 23077+6707
Kristina Monsch, Joshua B. Lovell, Karl R. Stapelfeldt +11
We present high-resolution () Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) imaging of the near edge-on () protoplanetary disk IRAS 23077…
On Convective Turnover Times and Dynamos In Low-Mass Stars
Seth Gossage, Rocio Kiman, Kristina Monsch +7
The relationship between magnetic activity and Rossby number is one way through which stellar dynamos can be understood. Using measured rotation rates and X-ray to bolometric lumin…
Heating of the Atmospheres of Short-orbit Exoplanets by Their Rapid Orbital Motion Through an Extreme Space Environment
Ofer Cohen, Alex Glocer, Cecilia Garraffo +4
Exoplanets with short orbit period reside very close to their host stars. They transition very rapidly between different sectors of the circumstellar space environment along their…
