Precise radial velocities of giant stars XIII. A second Jupiter orbiting in 4:3 resonance in the 7 CMa system
R. Luque, T. Trifonov, S. Reffert +8
We report the discovery of a second planet orbiting the K giant star 7 CMa based on 166 high-precision radial velocities obtained with Lick, HARPS, UCLES and SONG. The periodogram…
MASCARA-3b: A hot Jupiter transiting a bright F7 star in an aligned orbit
M. Hjorth, S. Albrecht, G. J. J. Talens +12
We report the discovery of MASCARA-3b, a hot Jupiter orbiting its bright (V = 8.33) late F-type host every days in an almost circular orbit ($e = 0.050^{+0.020…
Oscillations in the Sun with SONG: Setting the scale for asteroseismic investigations
M. Fredslund Andersen, P. Pallé, J. Jessen-Hansen +12
Context. We present the first high-cadence multi-wavelength radial-velocity observations of the Sun-as-a-star, carried out during 57 consecutive days using the stellar échelle spec…
Asteroseismology of the Hyades red giant and planet host epsilon Tauri
Torben Arentoft, Frank Grundahl, Timothy R. White +23
Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most other methods. Even in a well-s…
First detection of oscillations in the Halo giant HD 122563: validation of seismic scaling relations and new fundamental parameters
Orlagh Creevey, Frank Grundahl, Frédéric Thévenin +8
The nearby metal-poor giant HD122563 is an important astrophysical laboratory for which to test stellar atmospheric and interior physics. It is also a benchmark star for which to c…
Hardware and software for a robotic network of telescopes - SONG
M. F. Andersen, F. Grundahl, J. Christensen-Dalsgaard +7
SONG aims at setting up a network of small 1m telescopes around the globe to observe stars uninterrupted throughout days, weeks and even months. This paper describes the fundamenta…
The SONG prototype: Efficiency of a robotic telescope
M. F. Andersen, F. Grundahl, A. H. Beck +1
The Stellar Observations Network Group prototype telescope at the Teide Observatory has been operating in scientific mode since March 2014. The first year of observations has entir…
Conducting the SONG: The robotic nature and efficiency of a fully automated telescope
M. Fredslund Andersen, R. Handberg, E. Weiss +4
We present a description of "the Conductor", an automated software package which handles all observations at the first Stellar Observations Network Group (SONG) node telescope at t…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
