Simulated Coronal Mass Ejections on a young Solar-Type Star and the Associated Instantaneous Angular Momentum Loss
Yu Xu, Julián D. Alvarado-Gómez, Hui Tian +3
Coronal mass ejections (CMEs) on stars can change the stars' magnetic field configurations and mass loss rates during the eruption and propagation and therefore, may affect the sta…
The first evidence of tidally induced activity in a brown dwarf-M dwarf pair: A Chandra study of the NLTT 41135/41136 system
Nikoleta Ilić, Katja Poppenhaeger, Desmond Dsouza +3
The magnetic activity of low-mass stars changes as they age. The primary process decreasing the stellar activity level is the angular momentum loss via magnetized stellar wind. How…
Far beyond the Sun: II. Probing the stellar magnetism of the young Sun ι Horologii from the photosphere to its corona
E. M. Amazo-Gómez, J. D. Alvarado-Gómez, K. Poppenhaeger +14
A comprehensive multi-wavelength campaign has been carried out to probe stellar activity and variability in the young Sun-like star -Horologii. We present the results from long-…
Quantification of the environment of cool stars using numerical simulations
J. J. Chebly, J. D. Alvarado-Gómez, K. Poppenhaeger
Stars interact with their planets through gravitation, radiation, and magnetic fields. Although magnetic activity decreases with time, reducing associated high-energy (e.g., corona…
Tidal star-planet interaction and its observed impact on stellar activity in planet-hosting wide binary systems
Nikoleta Ilic, Katja Poppenhaeger, S. Marzieh Hosseini
Tidal interaction between an exoplanet and its host star is a possible pathway to transfer angular momentum between the planetary orbit and the stellar spin. In cases where the pla…
Simulating the Space Weather in the AU Mic System: Stellar Winds and Extreme Coronal Mass Ejections
Julián D. Alvarado-Gómez, Ofer Cohen, Jeremy J. Drake +7
Two close-in planets have been recently found around the M-dwarf flare star AU Microscopii (AU Mic). These Neptune-sized planets (AU Mic b and c) seem to be located very close to t…
