Improving radial velocity precision with CARMENES-PLUS:An upgrade of the near-infrared spectrograph cooling system
R. Varas, R. Calvo-Ortega, P. J. Amado +25
CARMENES is a dual-channel high-resolution spectrograph at the 3.5 m Calar Alto telescope designed to detect low-mass planets around late-type dwarfs by measuring their radial velo…

The CARMENES search for exoplanets around M dwarfs. The impact of rotation and magnetic fields on the radial velocity jitter in cool stars
H. L. Ruh, M. Zechmeister, A. Reiners +19
Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both instrumental and astrophysical sourc…
