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…
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…
The Space Weather of Proxima Centauri b
Cecilia Garraffo, Jeremy J. Drake, Ofer Cohen
A planet orbiting in the "habitable zone" of our closest neighboring star, Proxima Centauri, has recently been discovered, and the next natural question is whether or not Proxima b…
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…
Upgrading the Solar-Stellar Connection: News about activity in Cool Stars
H. M. Günther, K. Poppenhaeger, P. Testa +9
In this splinter session, ten speakers presented results on solar and stellar activity and how the two fields are connected. This was followed by a lively discussion and supplement…
The effect of limited spatial resolution of stellar surface magnetic field maps on MHD wind and coronal X-ray emission models
C. Garraffo, O. Cohen, J. J. Drake +1
We study the influence of the spatial resolution on scales of and smaller of solar surface magnetic field maps on global magnetohydrodynamic solar wind models, and on a model…
