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”. The whole group or the entire project is sometimes referred to as the “RVx” (now say the letter x) collaboration or project.

Latest update:

March 2019: We are moving on to our second phase or RVxTESS! After a successful splinter meeting at the Kepler Science Conference V, a group of us are proposing for CFHT time to use SPIRou to observe active M dwarfs simultaneously with TESS. This is a collaboration led by three PIs from three different countries (and three proposals): Junbo Zhang (NAOC), Claire Moutou (CFHT), and Ryan Cloutier (University of Toronto).

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.
