The X-Ray Sun in Time: A Study of the Long-Term Evolution of Coronae of Solar-Type Stars
- M. Güdel, E. Guinan, S. Skinner
- Physics
- 10 July 1997
We have used the ASCA and ROSAT X-ray satellites to probe the coronae of a sample of nine solar-like G stars. These stars are all ostensibly single with ages ranging from 70 Myr to 9 Gyr and have…
Coronal Evolution of the Sun in Time: High-Resolution X-Ray Spectroscopy of Solar Analogs with Different Ages
- A. Telleschi, M. Guedel, K. Briggs, M. Audard, J. Ness, S. Skinner
- Physics
- 20 March 2005
We investigate the long-term evolution of X-ray coronae of solar analogs based on high-resolution X-ray spectroscopy and photometry with XMM-Newton. Six nearby main-sequence G stars with ages between…
A high-sensitivity survey of radio continuum emission from Herbig Ae/Be stars
- S. Skinner, Alexander Brown, R. T. Stewart
- Physics
- 1992
We present results of a high-sensitivity VLA/Australia Telescope survey of radio continuum emission from the 57 Herbig Ae/Be stars and candidates in the 1984 catalog of Finkenzeller and Mundt. Twelve…
The XMM-Newton extended survey of the Taurus molecular cloud (XEST)
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newton X-ray…
THE TAURUS SPITZER SURVEY: NEW CANDIDATE TAURUS MEMBERS SELECTED USING SENSITIVE MID-INFRARED PHOTOMETRY
- L. Rebull, D. Padgett, S. Wolf
- Physics, Geology
- 16 November 2009
We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in seven mid- and far-infrared bands with the Spitzer Space Telescope. There are 215 previously…
Flares from small to large: X-ray spectroscopy of Proxima Centauri with XMM-Newton
- M. Guedel, M. Audard, F. Reale, S. Skinner, J. Linsky
- Physics
- 11 December 2003
We report results from a comprehensive study of the nearby M dwarf Proxima Centauri with the XMM-Newton satellite, using simultaneously its X-ray detectors and the Optical Monitor with its U band…
Discovery of a bipolar X-ray jet from the T Tauri star DG Tauri
- M. Guedel, S. Skinner, M. Audard, K. Briggs, S. Cabrit
- Physics
- 9 December 2007
Aims. We have obtained and analyzed Chandra ACIS-S observations of the strongly accreting classical T Tauri star DG Tau. Our principal goals are to map the immediate environment of the star to…
Million-Degree Plasma Pervading the Extended Orion Nebula
- M. Güdel, K. Briggs, T. Montmerle, M. Audard, L. Rebull, S. Skinner
- PhysicsScience
- 4 December 2007

Simultaneous chandra and vla observations of young stars and protostars in rho ophiuchus cloud core a
- M. Gagne, S. Skinner, Kathryne J Daniel
- Physics
- 24 May 2004
A 96 ks Chandra X-ray observation of ρ Ophiuchus cloud core A detected 87 sources, of which 60 were identified with counterparts at other wavelengths. The X-ray detections include 12 of 14 known…
X-rays from T Tauri: a test case for accreting T Tauri stars
- M. Guedel, S. Skinner, Ny
- Physics
- 20 December 2006
Context. The generation of X-rays in accreting T Tauri stars (TTS) is thought to be predominantly due to energy dissipation in magnetic elds, but alternative X-ray generation mechanisms have been…
