Accurate calibration spectra for precision radial velocities -- Iodine absorption referenced by a laser frequency comb

Ansgar Reiners, Michael Debus, Sebastian Schäfer +2

Astronomical spectrographs require frequency calibration through sources like hollow-cathode lamps or absorption-gas cells. Laser frequency combs (LFCs) provide highest accuracy bu…

The CARMENES search for exoplanets around M dwarfs. Measuring precise radial velocities in the near infrared: the example of the super-Earth CD Cet b

F. F. Bauer, M. Zechmeister, A. Kaminski +26

The high-resolution, dual channel, visible and near-infrared spectrograph CARMENES offers exciting opportunities for stellar and exoplanetary research on M dwarfs. In this work we…

A giant exoplanet orbiting a very low-mass star challenges planet formation models

J. C. Morales, A. J. Mustill, I. Ribas +179

Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…

The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf

A. Reiners, I. Ribas, M. Zechmeister +169

We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…

A much lower density for the transiting extrasolar planet WASP-7

John Southworth, M. Dominik, U. G. Jorgensen +29

We present the first high-precision photometry of the transiting extrasolar planetary system WASP-7, obtained using telescope defocussing techniques and reaching a scatter of 0.68…
