A Chandra Observation of the Eclipsing Wolf-Rayet Binary CQ Cep
S. L. Skinner, S. A. Zhekov, M. Guedel +1
The short-period (1.64 d) near-contact eclipsing WN6+O9 binary system CQ Cep provides an ideal laboratory for testing the predictions of X-ray colliding wind shock theory at close…
X-ray emission from an FU Ori star in early outburst: HBC 722
Armin Liebhart, Manuel Guedel, Stephen Skinner +1
Aims: We conducted the first X-ray observations of the newly erupting FU Ori-type outburst in HBC 722 (V2493 Cyg) with the aim to characterize its X-ray behavior and near-stellar e…
Astrophysical Conditions for Planetary Habitability
M. Guedel, R. Dvorak, N. Erkaev +7
With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal…
First Detection of Thermal Radio Emission from Solar-Type Stars with the Karl G. Jansky Very Large Array
Jackie Villadsen, Gregg Hallinan, Stephen Bourke +2
We present the first detections of thermal radio emission from the atmospheres of solar-type stars τ Cet, η Cas A, and 40 Eri A. These stars all resemble the Sun in age and level o…
Wideband Dynamic Radio Spectra of Two Ultra-cool dwarfs
C. Lynch, R. L. Mutel, M. Gudel
A number of radio-loud ultra cool dwarf stars (UCD) exhibit both continuous broadband and highly polarized pulsed radio emission. In order to determine the nature of the emission a…
Chandra Resolves the T Tauri Binary System RW Aur
Stephen L. Skinner, Manuel Guedel
RW Aur is a multiple T Tauri system consisting of an early-K type primary (A) and a K5 companion (B) at a separation of 1.4 arcsec. RW Aur A drives a bipolar optical jet that is we…
Jets and Outflows From Star to Cloud: Observations Confront Theory
A. Frank, T. P. Ray, S. Cabrit +10
In this review we focus on the role jets and outflows play in the star and planet formation process. Our essential question can be posed as follows: are jets/outflows merely an epi…
An X-ray and Infrared Survey of the Lynds 1228 Cloud Core
Stephen Skinner, Luisa Rebull, Manuel Guedel
The nearby Lynds 1228 (L1228) dark cloud at a distance of ~200 pc is known to harbor several young stars including the driving sources of the giant HH 199 and HH 200 Herbig-Haro ou…
Atomic jet from SMM1 (FIRS1) in Serpens uncovers non-coeval binary companion
O. Dionatos, J. K. Jørgensen, P. S. Teixeira +2
We report on the detection of an atomic jet associated with the protostellar source SMM1 (FIRS1) in Serpens. The jet is revealed in [FeII] and [NeII] line maps observed with Spitze…
