X-ray Irradiation of the Giant Planet Orbiting the T Tauri Star TAP 26
Stephen L. Skinner, Manuel Guedel
We present new Chandra X-ray observations of TAP 26, a ~17 Myr old magnetically-active weak-lined T Tauri star that has been reported to host a massive planet in a 10.8 day orbit.…
X-ray Observations of the Enigmatic Wolf-Rayet System Theta Mus: Two's Company But Three's a Crowd
Stephen L. Skinner, Svetozar A. Zhekov, Manuel Guedel +1
Theta Mus is a remarkable spectroscopic binary (SB) consisting of a carbon-type Wolf-Rayet star and OV companion (WC6+O6-7V) in a 19-day orbit. In addition an O-supergiant is visua…
HST UV Spectroscopy of the Planet-Hosting T Tauri Star PDS 70
Stephen L. Skinner, Marc Audard
We summarize Hubble Space Telescope (HST) UV observations of the weak-lined T Tauri star (wTTS) PDS 70 obtained with the Space Telescope Imaging Spectrograph (STIS). These observat…
Chandra revisits WR48a: testing colliding wind models in massive binaries
Svetozar A. Zhekov, Marc Gagne, Stephen L. Skinner
We present results of new Chandra High-Energy Transmission Grating (HETG) observations (2019 November - December) of the massive Wolf-Rayet (WR) binary WR 48a. Analysis of these hi…
Chandra X-ray Observations of V830 Tau: A T Tauri Star Hosting an Evanescent Planet
Stephen L. Skinner, Manuel Guedel
A radial velocity study by Donati et al. (2016) reported the detection of a close-in giant planet in a 4.93 d orbit around the ~2 Myr old weak-lined T Tauri star V830 Tau. Because…
Chandra Resolves the Double FU Orionis System RNO 1B/1C in X-rays
Stephen L. Skinner, Manuel Guedel
We present new Chandra X-ray observations of the close pair of young stars RNO 1B and 1C (6 separation) located in the L1287 cloud. RNO 1B erupted in 1978 - 1990 and is classif…
