Evidence of a Massive Stellar Disruption in the X-ray Spectrum of ASASSN-14li
J. M. Miller, B. Mockler, E. Ramirez-Ruiz +7
The proximity and duration of the tidal disruption event (TDE) ASASSN-14li led to the discovery of narrow, blue-shifted absorption lines in X-rays and UV. The gas seen in X-ray abs…
Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
Three-dimensional, Time-dependent MHD Simulation of Disk-Magnetosphere-Stellar Wind Interaction in a T Tauri, Protoplanetary System
Ofer Cohen, Cecilia Garraffo, Jeremy Drake +4
We present a three-dimensional, time-dependent, MHD simulation of the short-term interaction between a protoplanetary disk and the stellar corona in a T Tauri system. The simulatio…
Non-thermal -rays from pulsation-driven shocks in Cepheids
Federico Fraschetti, Konstantina Anastasopoulou, Jeremy J. Drake +1
Rapid X-ray phase-dependent flux enhancement in the archetype classical Cepheid star ~Cep was observed by XMM-Newton and Chandra. We jointly analyse thermal and non-thermal comp…
Revisiting the space weather environment of Proxima Centauri b
Cecilia Garraffo, Julián D. Alvarado-Gómez, Ofer Cohen +1
Close-in planets orbiting around low-mass stars are exposed to intense energetic photon and particle radiation and harsh space weather. We have modeled such conditions for Proxima…
Line Emission Mapper (LEM): Probing the physics of cosmic ecosystems
Ralph Kraft, Maxim Markevitch, Caroline Kilbourne +107
The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe's structure formation. It will also provide transformative…
