High-Energy Photon and Particle Effects onExoplanet Atmospheres and Habitability
Jeremy J. Drake, Julián D. Alvarado-Gómez, Vladimir Airapetian +41
It is now recognized that energetic stellar photon and particle radiation evaporates and erodes planetary atmospheres and controls upper atmospheric chemistry. Key exoplanet host s…
Three X-ray Flares Near Primary Eclipse of the RS CVn Binary XY UMa
Hang Gong, Rachel Osten, Thomas Maccarone +3
We report on an archival X-ray observation of the eclipsing RS CVn binary XY UMa ( 0.48d). In two ACIS observations spanning 200 ks and almost…
Next Generation Very Large Array Memo No. 9 Science Working Group 4: Time Domain, Fundamental Physics, and Cosmology
Geoffrey C. Bower, Paul Demorest, James Braatz +20
We report here on key science topics for the Next Generation Very Large Array in the areas of time domain, fundamental physics, and cosmology. Key science cases considered are puls…
Stellar flares observed by LOFT: implications for the physics of coronae and for the "space weather" environment of extrasolar planets
S. A. Drake, E. Behar, J. G. Doyle +7
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
A prompt radio transient associated with a gamma-ray superflare from the young M dwarf binary DG CVn
R. P. Fender, G. E. Anderson, R. Osten +4
On 2014 April 23, the Swift satellite detected a gamma-ray superflare from the nearby star system DG CVn. This system comprises a M-dwarf binary with extreme properties: it is very…
Wide-band Simultaneous Observations of Pulsars: Disentangling Dispersion Measure and Profile Variations
T. E. Hassall, B. W. Stappers, J. W. T. Hessels +91
Dispersion in the interstellar medium is a well known phenomenon that follows a simple relationship, which has been used to predict the time delay of dispersed radio pulses since t…
