Characterization of the radial velocity signal induced by rotation in late-type dwarfs [PDF]
, 2017 We investigate the activity induced signals related to rotation in late type stars (FGKM). We analyse the Ca II H&K, the H alpha and the radial velocity time-series of 55 stars using the spectra from the HARPS public database and the light-curves ...

CEPHEID PULSATIONS FROM RADIAL VELOCITY MEASUREMENTS
Odessa Astronomical Publications, 2017 We discuss the results of our many-year program of Cepheid radial velocities concerning the Hertzsprung sequence in radial-velocity curves, double-mode Cepheids, the period-radius relation, binary Cepheids.

The Death of Vulcan: NEID Reveals That the Planet Candidate Orbiting HD 26965 Is Stellar Activity
The Astronomical JournalWe revisit the long-studied radial velocity (RV) target HD 26965 using recent observations from the NASA-NSF “NEID” precision Doppler facility. Leveraging a suite of classical activity indicators, combined with line-by-line RV analyses, we demonstrate ...

The VLT-FLAMES Tarantula Survey XVIII. Classifications and radial velocities of the B-type stars [PDF]
, 2015 We present spectral classifications for 438 B-type stars observed as part of the VLT-FLAMES Tarantula Survey (VFTS) in the 30 Doradus region of the Large Magellanic Cloud. Radial velocities are provided for 307 apparently single stars, and for 99 targets

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
