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…
An MHD Simulation of the Possible Modulations of Stellar CMEs Radio Observations by an Exoplanetary Magnetosphere
Soumitra Hazra, Ofer Cohen, Igor V. Sokolov
Type II radio bursts are the indicator of adverse space weather in a stellar system. These radio bursts are the consequence of shock wave acceleration due to the coronal mass eject…
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…
The Revolution Revolution: magnetic morphology driven spin-down
C. Garraffo, J. J. Drake, A. Dotter +6
Observations of young open clusters show a bimodal distribution of rotation periods that has been difficult to explain with existing stellar spin-down models. Detailed MHD stellar…
Giant coronal loops dominate the quiescent X-ray emission in rapidly rotating M stars
O. Cohen, R. Yadav, C. Garraffo +5
Observations indicate that magnetic fields in rapidly rotating stars are very strong, on both small and large scales. What is the nature of the resulting corona? Here we seek to sh…
