RVxTESS & RVxK2

Simultaneous Radial Velocity Observations with TESS & Kepler/K2 Campaign 16

Welcome to RVxTESS and RVxK2

RVxTESS and RVxK2 are simultaneous radial velocity observing programs with TESS (starting July 2018) and Kepler/K2 Campaign 16 (December 7, 2017 – February 25, 2018), respectively. The team is led by Dr. Sharon Xuesong Wang at Carnegie DTM, with team members across the world. Participating telescopes and instruments including Magellan/PFS, Keck/HIRES, APF, IRTF/iSHELL, SONG, MINERVA, and PARAS. We welcome new collaborations any time!

Why the name?

RVx = RV times. “x” emphasizes the simultaneity of the RVs and TESS/Kepler photometry in time. It is a silent “x” though, for simplicity: it’s pronounced “RV K2” and “RV TESS”.

Latest update:

July/August 2018: RVxTESS is happening! We are observing HD 6793 (giant) and HD 5562 (subgiant) simultaneously with Magellan Planet Finder Spectrograph (PFS) during TESS sector 1 and 2.

March 2018, RVxK2: We have concluded our RVxK2 runs! Our Keck/HIRES high cadence nights were terribly snowed out, unfortunately, but we have successfully gather data on HIP 44072 and HD 76445 for a few hours. Please stay tuned for science results and data release! Our target list and telescope coverage is available here.

Our team:

Our RVxK2 team include: Jason Wright , John Johnson, Fabienne Bastien, Jacob Luhn, Jennifer Burt, Elisabeth Newton, Jason Eastman, Johanna Teske, Heather Cegla, Peter Plavchan, Angelle Tanner, Jonathan Gagné, Andrew Vanderburg, Courtney Dressing, Paul Robertson, Stephen Kane, Abhijit Chakraborty, Frank Grundahl, Bryson Cale, Brad Holden, Howard Isaacson, Andrew Howard, and Paul Butler.
