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…
Experimental evidence for coronal mass ejection suppression in strong stellar magnetic fields
S. N. Chen, K. Burdonov, W. Yao +10
Solar coronal mass ejections (CME) are routinely observed, but as of yet there exist few convincing detections of stellar CMEs. A reason for this could be the stronger magnetic fie…
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…
The Magnetic Nature of the Cataclysmic Variable Period Gap
C. Garraffo, J. J. Drake, J. D. Alvarado-Gomez +2
One of the most important problems in the context of cataclysmic variables (CVs) is the lack of observations of systems with periods between 2 and 3.12 hours, known as the period g…
Mottled protoplanetary disk ionization by magnetically-channeled T Tauri star energetic particles
Federico Fraschetti, Jeremy J. Drake, Ofer Cohen +1
The evolution of protoplanetary disks is believed to be driven largely by angular momentum transport resulting from magnetized disk winds and turbulent viscosity. The ionization of…
Simulating the environment around planet-hosting stars - II. Stellar winds and inner astrospheres
J. D. Alvarado-Gómez, G. A. J. Hussain, O. Cohen +4
We present the results of a comprehensive numerical simulation of the environment around three exoplanet-host stars (HD 1237, HD 22049, and HD 147513). Our simulations consider one…
Activity and Magnetic Field Structure of the Sun-Like Planet Hosting Star HD 1237
J. D. Alvarado-Gómez, G. A. J. Hussain, J. Grunhut +13
We analyse the magnetic activity characteristics of the planet hosting Sun-like star, HD 1237, using HARPS spectro-polarimetric time-series data. We find evidence of rotational mod…
