pyaneti: a fast and powerful software suite for multiplanet radial velocity and transit fitting [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Transiting exoplanet parameter estimation from time-series photometry and Doppler spectroscopy is fundamental to study planets' internal structures and compositions. Here we present the code pyaneti, a powerful and user-friendly software suite to perform

WIYN Open Cluster Study. XXXVIII. Stellar Radial Velocities in the Young Open Cluster M35 (NGC 2168) [PDF]
, 2009 We present 5201 radial-velocity measurements of 1144 stars, as part of an ongoing study of the young (150 Myr) open cluster M35 (NGC 2168). We have observed M35 since 1997, using the Hydra Multi-Object Spectrograph on the WIYN 3.5m telescope. Our stellar

AESTRA: Deep Learning for Precise Radial Velocity Estimation in the Presence of Stellar Activity
The Astronomical Journal, 2023 Stellar activity interferes with precise radial velocity measurements and limits our ability to detect and characterize planets, in particular Earth-like planets.

Radial Velocities with Gaia [PDF]
Proceedings of the International Astronomical Union, 2004 Gaia is a mission to map the positions and determine the velocities of 1 billion stars in the Galaxy, in order to determine how it was formed and how it has evolved. Spectroscopy provides one component of the space velocities for 200 million objects, and, in addition, astrophysical information such as temperature and metallicity for the brighter 40 ...

Radial velocity follow-up of GJ1132 with HARPS [PDF]
Astronomy & Astrophysics, 2018 The source GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the HARPS velocimeter. We now confirm the detection of GJ1132b with radial velocities alone.

Fundamental parameters of Cepheids. V. Additional photometry and radial velocity for southern Cepheids [PDF]
, 2002 I present photometric and radial velocity data for Galactic Cepheids, most of them being in the southern hemisphere. There are 1250 Geneva 7-color photometric measurements for 62 Cepheids, the average uncertainty per measurement is better than 0.01 mag ...

Measurements of the Reynolds stress in the turbulent premixed flame
Nihon Kikai Gakkai ronbunshu, 2021 It has been shown in our previous study that the bi-modal distribution is seen in the radial component of the gas velocity obtained in the turbulent flame brush, implying that the shear component of the Reynolds stress conditioned on the unburnt mixture ...
