XUV exposed non-hydrostatic hydrogen-rich upper atmospheres of terrestrial planets. Part I: Atmospheric expansion and thermal escape

N. V. Erkaev, H. Lammer, P. Odert +6

The recently discovered low-density "super-Earths" Kepler-11b, Kepler-11f, Kepler-11d, Kepler-11e, and planets such as GJ 1214b represent most likely planets which are surrounded b…

XUV exposed, non-hydrostatic hydrogen-rich upper atmospheres of terrestrial planets II: Hydrogen coronae and ion escape

K. G. Kislyakova, H. Lammer, M. Holmström +8

We study the interactions between the stellar wind plasma flow of a typical M star, such as GJ 436, and hydrogen-rich upper atmospheres of an Earth-like planet and a "super-Earth"…

The Herschel DIGIT Survey of Weak-line T Tauri Stars: implications for disk evolution and dissipation

Lucas A. Cieza, Johan Olofsson, Paul M. Harvey +8

As part of the "Dust, Ice, and Gas In Time (DIGIT)" Herschel Open Time Key Program, we present Herschel photometry (at 70, 160, 250, 350 and 500 micron) of 31 Weak-Line T Tauri sta…

On the origin of [Ne II] emission in young stars: mid-infrared and optical observations with the Very Large Telescope

C. Baldovin-Saavedra, M. Audard, A. Carmona +5

{Abridged version for ArXiv}. We provide direct constraints on the origin of the [Ne II] emission in 15 young stars using high-spatial and spectral resolution observations with VIS…

The close T Tauri binary system V4046 Sgr: Rotationally modulated X-ray emission from accretion shocks

C. Argiroffi, A. Maggio, T. Montmerle +11

We report initial results from a quasi-simultaneous X-ray/optical observing campaign targeting V4046 Sgr, a close, synchronous-rotating classical T Tauri star (CTTS) binary in whic…

New X-ray Detections of WNL Stars

Stephen L. Skinner, Svetozar A. Zhekov, Manuel Guedel +2

Previous studies have demonstrated that putatively single nitrogen-type Wolf-Rayet stars (WN stars) without known companions are X-ray sources. However, almost all WN star X-ray de…
