The Bipolar X-Ray Jet of the Classical T Tauri Star DG Tau
M. Guedel, M. Audard, F. Bacciotti +18
We report on new X-ray observations of the classical T Tauri star DG Tau. DG Tau drives a collimated bi-polar jet known to be a source of X-ray emission perhaps driven by internal…
APOSTLE Observations of GJ 1214b: System Parameters and Evidence for Stellar Activity
P. Kundurthy, E. Agol, A. C. Becker +3
We present three transits of GJ 1214b, observed as part of the Apache Point Observatory Survey of Transit Lightcurves of Exoplanets (APOSTLE). We used APOSTLE r-band lightcurves in…
Discovery and Mass Measurements of a Cold, 10-Earth Mass Planet and Its Host Star
Y. Muraki, C. Han, D. P. Bennett +125
We present the discovery and mass measurement of the cold, low-mass planet MOA-2009-BLG-266Lb, made with the gravitational microlensing method. This planet has a mass of m_p = 10.4…
Extended Mid-Infrared Aromatic Feature Emission in M 82
C. W. Engelbracht, P. Kundurthy, K. D. Gordon +19
We present new images (groundbased optical and mid-infrared (MIR) from the Spitzer Space Telescope) and spectra (from Spitzer) of the archetypal starburst galaxy M 82. The Spitzer…
