DN Tauri - coronal activity and accretion in a young low-mass CTTS
J. Robrade, M. Guedel, H. M. Guenther +1
We present a deep XMM-Newton observation of DN Tau, a young M0-type accreting CTTS and investigate its X-ray properties and X-ray generating mechanisms. Specifically we examine the…
Constraining Stellar Winds of Young Sun-like Stars
Colin P. Johnstone, Theresa Lüftinger, Manuel Güdel +1
As part of the project Pathways to Habitability (http://path.univie.ac.at/), we study the properties of the stellar winds of low-mass and Sun-like stars, and their influences on th…
The magnetosphere of the close accreting PMS binary V4046 Sgr AB
S. G. Gregory, V. R. Holzwarth, J. -F. Donati +14
We present a preliminary 3D potential field extrapolation model of the joint magnetosphere of the close accreting PMS binary V4046 Sgr. The model is derived from magnetic maps obta…
The magnetosphere of the close accreting PMS binary V4046 Sgr
S. G. Gregory, V. R. Holzwarth, J. -F. Donati +14
V4046 Sagittarii AB is a close short-period classical T Tauri binary. It is a circularised and synchronised system accreting from a circumbinary disk. In 2009 it was observed as pa…
DIGIT survey of far-infrared lines from protoplanetary disks I
D. Fedele, S. Bruderer, E. F. van Dishoeck +10
[abridged] We present far-infrared spectroscopic observations of PMS stars taken with Herschel/PACS as part of the DIGIT key project. The sample includes 22 Herbig AeBe and 8 T Tau…
Escape of the martian protoatmosphere and initial water inventory
N. V. Erkaev, H. Lammer, L. Elkins-Tanton +8
Latest research in planet formation indicate that Mars formed within a few million years (Myr) and remained a planetary embryo that never grew to a more massive planet. It can also…
The Hot and Energetic Universe: Star formation and evolution
S. Sciortino, G. Rauw, M. Audard +16
Stars over a wide range of masses and evolutionary stages are nowadays known to emit X-rays. This X-ray emission is a unique probe of the most energetic phenomena occurring in the…
The Hot and Energetic Universe: Solar system and exoplanets
G. Branduardi-Raymont, S. Sciortino, K. Dennerl +11
The high resolution non-dispersive spectroscopy and unprecedented sensitivity of Athena+ will revolutionize solar system observing: the origin of the ions producing Jupiter's X-ray…
An Analysis of the Environments of FU Orionis Objects with Herschel
Joel D. Green, Neal J. Evans, 'Agnes K'osp'al +13
We present Herschel-HIFI, SPIRE, and PACS 50-670 μm imaging and spectroscopy of six FU Orionis-type objects and candidates (FU Orionis, V1735 Cyg, V1515 Cyg, V1057 Cyg, V1331 Cyg,…
Characterizing Exoplanets in the Visible and Infrared: A Spectrometer Concept for the EChO Space Mission
A. M. Glauser, R. van Boekel, O. Krause +30
Transit-spectroscopy of exoplanets is one of the key observational techniques to characterize the extrasolar planet and its atmosphere. The observational challenges of these measur…
X-ray Irradiation of the LkCa 15 Protoplanetary Disk
Stephen L. Skinner, Manuel Guedel
LkCa 15 in the Taurus star-forming region has recently gained attention as the first accreting T Tauri star likely to host a young protoplanet. High spatial resolution infrared obs…
Discovery of X-ray emission from young suns in the Small Magellanic Cloud
L. M. Oskinova, W. Sun, C. J. Evans +11
We report the discovery of extended X-ray emission within the young star cluster NGC 602 in the Wing of the Small Magellanic Cloud (SMC) based on observations obtained with the Cha…
