Precise Masses in the WASP-47 System

Andrew Vanderburg, Juliette C. Becker, Lars A. Buchhave +32

We present precise radial velocity observations of WASP-47, a star known to host a hot Jupiter, a distant Jovian companion, and, uniquely, two additional transiting planets in shor…

Precise masses for the transiting planetary system HD 106315 with HARPS

S. C. C. Barros, H. Gosselin, J. Lillo-Box +45

The multi-planetary system HD 106315 was recently found in K2 data . The planets have periods of and days, and radii of a…

Insights on the Spectral Signatures of Stellar Activity and Planets from PCA

Allen B. Davis, Jessi Cisewski, Xavier Dumusque +2

Photospheric velocities and stellar activity features such as spots and faculae produce measurable radial velocity signals that currently obscure the detection of sub-meter-per-sec…

Understanding stellar activity-induced radial velocity jitter using simultaneous K2 photometry and HARPS RV measurements

M. Oshagh, N. C. Santos, P. Figueira +15

One of the best ways to improve our understanding of the stellar activity-induced signal in radial velocity (RV) measurements is through simultaneous high-precision photometric and…

An extreme planetary system around HD219828. One long-period super Jupiter to a hot-neptune host star

N. C. Santos, A. Santerne, J. P. Faria +19

With about 2000 extrasolar planets confirmed, the results show that planetary systems have a whole range of unexpected properties. We present a full investigation of the HD219828 s…

State of the Field: Extreme Precision Radial Velocities

Debra Fischer, Guillem Anglada-Escude, Pamela Arriagada +53

The Second Workshop on Extreme Precision Radial Velocities defined circa 2015 the state of the art Doppler precision and identified the critical path challenges for reaching 10 cm/…
