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…
Non-radial oscillations mimicking a brown dwarf orbiting the cluster giant NGC 4349 No. 127
Dane Spaeth, Sabine Reffert, Emily L. Hunt +2
Several evolved stars have been found to exhibit long-period radial velocity variations that cannot be explained by planetary or brown dwarf companions. Non-radial oscillations cau…
Revisiting the dynamical masses of the transiting planets in the young AU Mic system: Potential AU Mic b inflation at 20 Myr
M. Mallorquín, V. J. S. Béjar, N. Lodieu +26
Understanding planet formation is important in the context of the origin of planetary systems in general and of the Solar System in particular, as well as to predict the likelihood…
The CARMENES search for exoplanets around M dwarfs. Revisiting the GJ 581 multi-planetary system with new Doppler measurements from CARMENES, HARPS, and HIRES
A. von Stauffenberg, T. Trifonov, A. Quirrenbach +18
GJ 581 is a nearby M dwarf known to host a packed multiple planet system with 2 super-Earths and a Neptune-mass planet. We present new orbital analyses of the system, utilizing rec…
Optical ray tracing of echelle spectrographs applied to the wavelength solution for precise radial velocities
Marcelo Tala Pinto, Adrian Kaminski, Andreas Quirrenbach +1
We present , a ray tracing software package that computes the path of rays through echelle spectrographs. Our algorithm is based on sequential direct tracing with Se…
