Deriving High-Precision Radial Velocities
Pedro Figueira
This chapter describes briefly the key aspects behind the derivation of precise radial velocities. I start by defining radial velocity precision in the context of astrophysics in g…
The Tc trend in the Zetta Reticuli system: N spectra - N trends
V. Adibekyan, P. Figueira, E. Delgado Mena +4
It is suggested that the chemical abundance trend with the condensation temperature, Tc , can be a signature of rocky planet formation or accretion. Recently, a strong Tc trend was…
How alien can alien worlds be?
V. Adibekyan, P. Figueira, N. C. Santos
In an attempt to select stars that can host planets with characteristics similar to our own, we selected seven solar-type stars known to host planets in the habitable zone and for…
The TROY project: Searching for co-orbital bodies to known planets. I. Project goals and first results from archival radial velocity
J. Lillo-Box, D. Barrado, P. Figueira +5
The detection of Earth-like planets, exocomets or Kuiper belts show that the different components found in the solar system should also be present in other planetary systems. Troja…
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…
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…
