Brief Overview:
Research Activities in Star Formation
My group works in the field of star formation, young stars and stellar environments such as accretion disks,
jets, and also young planetary atmospheres. Since the mid 90ies, we have been studying implications of stellar
magnetic activity on young stellar environments, with a special focus on high-energy radiation and high-energy particles.
We are making use of various large observatories such as XMM-Newton, Chandra, the Very Large Array, or the Spitzer Space Telescope, and
will focus on ALMA, Herschel, and the James Webb Space Telescope in the near future. These efforts are supported
by our involvement in the latter projects, in particular collaborations within the guaranteed time of Herschel, legacy-type
Herschel projects, and our direct involvement in the Mid InfraRed Instrument on JWST. Present group members are
Manuel Güdel, Kevin Briggs and Adrian Glauser. A buildup of a larger group is in preparation.

Large Projects
MIRI: MidInfraRed Instrument on the James Webb
Space Telescope, European Co-PI; MIRI is one of the
three scientific instruments on JWST; complementary to NIRCAM and Nirspec, it covers the mid-infrared range, providing 0.2" resolution imaging
and mid-IR spectroscopy. Roughly speaking, MIRI is a successor to Spitzer's IRAC and IRS instruments but fed by
a 6.5 meter mirror, making it an extremely sensitive instrument. Switzerland
(through the Paul Scherrer Institut) contributes significant instrumentation hardware, in particular cryo-harness,
a contamination control cover, and a test chamber. The Swiss MIRI lead has been transferred to ETH Zürich in 2008.
Our group will continue support of MIRI through the calibration campaign, the in-orbit verification phase, and
then the science phase. Launch is planned for 2013.
RGS: Reflection Grating
Spectrometer on XMM-Newton, Consortium member. High-resolution X-ray spectroscopy
of astrophysical objects has become possible only with the RGS on XMM-Newton (launch in 1999) and the grating spectrometers on Chandra. Emission-line
spectroscopy has been used to study the composition and thermal structure of astrophysical plasmas.
XEST: XMM-Newton Extended Survey of
the Taurus Molecular Cloud, PI; XEST is a large X-ray survey of the low-mass star formation region in Taurus, proposed in 2003 and
so far comprising 31 half-degree exposures. Discoveries include a soft excess in classical T Tauri stars, a new type of X-ray source probably related
to outflows, several correlations between X-ray properties and stellar properties, and numerous brown-dwarf X-ray sources. The initial
15 papers related to this project were published in an A&A special issue (June 2007).
XSO: XMM-Newton Survey of the Orion Region, PI. This project studies about 1500 forming stars
in and around the Orion Nebula in X-rays, a region spanning about 2 degrees in north-south direction. A first highlight
was the discovery of a diffuse plasma cloud pervading the Orion Nebula, published in the journal Science (Nov. 29, 2007).
Spitzer Taurus Legacy Program, Co-I (PI: D. Padgett/Caltech).
The Spitzer Taurus survey has mapped 45 sq. degrees of the Taurus star-forming region in all photometric bands of the
IRAC and MIPS instruments. Several hundred thousand sources are the subject of an ongoing deep investigation to study
dust and gas environments of young stars.
HEXOS: Herschel GT Observations of Extraordinary Sources: The Orion and Sgr B2 Star Forming Regions, Co-I
(PI: T. Bergin/Wisconsin). This is a project within the guaranteed time section of Herschel. It is a pivotal and basic effort to
obtain an inventory of all molecular transitions relevant in warm molecular clouds, to probe chemistry in young stellar environments,
and to study the influence of stellar radiation on the cool molecular gas. Herschel is scheduled for launch in 2008.
DIGIT: Dust, Ice, and Gas in Time, Herschel key program, Co-I (PI: N. Evans/Austin).
Accepted as a Herschel Open-Time Key Project to study the evolution of stellar environments during all stages of the star formation process,
in particular interactions between dust, gas, and ice phases in molecular envelopes and circumstellar disks. Herschel is scheduled for launch in 2008.
The Great Nebula in Carina:
Protoplanetary Disks to Starburst Galaxies, Co-I (PI: L. Townsley/PennState). Proposed and approved in 2007 as a Very Large Program for
Chandra to study many aspects of star formation in an extremely massive star-forming region.
XMM-Newton GT projects on stellar X-ray emission, PI and CoI. Many stellar XMM-Newton projects have been conducted as part of the
guaranteed time of the XMM-Newton RGS instrument, starting in spring 2000. Highlights include a study of the long-term evolution of solar analogs,
density diagnostics of coronal gas, a spatially resolved eclipse map of a young solar analog, new coronal abundance systematics, etc.
