A Candidate Young Massive Planet in Orbit around the Classical T Tauri Star CI Tau

Christopher M. Johns-Krull, Jacob N. McLane, L. Prato +10

The ~2 Myr old classical T Tauri star CI Tau shows periodic variability in its radial velocity (RV) variations measured at infrared (IR) and optical wavelengths. We find that these…

Follow-Up Observations of PTFO 8-8695: A 3 MYr Old T-Tauri Star Hosting a Jupiter-mass Planetary Candidate

David R. Ciardi, J. C. van Eyken, J. W. Barnes +13

We present Spitzer 4.5\micron\ light curve observations, Keck NIRSPEC radial velocity observations, and LCOGT optical light curve observations of PTFO~8-8695, which may host a Jupi…

A Search for Giant Planet Companions to T Tauri Stars

Christopher J. Crockett, Naved I. Mahmud, L. Prato +4

We present results from an ongoing multiwavelength radial velocity (RV) survey of the Taurus-Auriga star forming region as part of our effort to identify pre--main sequence giant p…

Starspot-induced optical and infrared radial velocity variability in T Tauri star Hubble 4

Naved I. Mahmud, Christopher J. Crockett, Christopher M. Johns-Krull +4

We report optical (6150 Ang) and K-band (2.3 micron) radial velocities obtained over two years for the pre-main sequence weak-lined T Tauri star Hubble I 4. We detect periodic and…

Precision radial velocities with CSHELL

Christopher J. Crockett, Naved I. Mahmud, Lisa Prato +3

Radial velocity identification of extrasolar planets has historically been dominated by optical surveys. Interest in expanding exoplanet searches to M dwarfs and young stars, howev…
