H-alpha Variability in PTFO8-8695 and the Possible Direct Detection of Emission from a 2 Million Year Old Evaporating Hot Jupiter
Christopher M. Johns-Krull, Lisa Prato, Jacob N. McLane +9
We use high time cadence, high spectral resolution optical observations to detect excess H-alpha emission from the 2 - 3 Myr old weak lined T Tauri star PTFO8-8695. This excess emi…
Precise Near-Infrared Radial Velocities
Peter Plavchan, Peter Gao, Jonathan Gagne +31
We present the results of two 2.3 micron near-infrared radial velocity surveys to detect exoplanets around 36 nearby and young M dwarfs. We use the CSHELL spectrograph (R ~46,000)…
A High-Precision NIR Survey for RV Variable Low-Mass Stars
Jonathan Gagné, Peter Plavchan, Peter Gao +26
We present the results of a precise near-infrared (NIR) radial velocity (RV) survey of 32 low-mass stars with spectral types K2-M4 using CSHELL at the NASA IRTF in the -band wit…
