We present Rossiter-McLaughlin observations of the transiting super-Earth 55 Cnc e collected during six transit events between 2012 January and 2013 November...
Rotationally resolved spectroscopy of (20000) Varuna in the near-infrared
Context. Models of the escape and retention of volatiles by minor icy objects exclude any presence of volatile ices on the surface of trans-Neptunian objects...
Rotationally resolved spectroscopy of dwarf planet (136472) Makemake
Context. Icy dwarf planets are key for studying the chemical and physical states of ices in the outer solar system. The study of secular and rotational...
Ruling out the Orbital Decay of the WASP-43b Exoplanet
We present 15 new transit observations of the exoplanet WASP-43b in the i‧, g‧, and R filters with the 1.0 m telescopes of Las Cumbres Observatory Global...
Scaling slowly rotating asteroids with stellar occultations
Context. As evidenced by recent survey results, the majority of asteroids are slow rotators (spin periods longer than 12 h), but lack spin and shape models...
SDSS-IV MaStar: A Large and Comprehensive Empirical Stellar Spectral Library—First Release
We present the first release of the MaNGA Stellar Library (MaStar), which is a large, well-calibrated, high-quality empirical library covering the wavelength...
Search and characterization of T-type planetary mass candidates in the σ Orionis cluster
Context. The proper characterization of the least massive population of the young σ Orionis star cluster is required to understand the form of the cluster mass...
Search for planets around stars with wide brown dwarfs
Aims: This work aims to better understand the role of wide brown dwarf companions in planetary systems. Methods: We obtained high-resolution spectra of six...
Search for radial velocity variations in eight M-dwarfs with NIRSPEC/Keck II
Context. Radial velocity (RV) measurements from near-infrared spectra have become a potentially powerful tool to search for planets around cool stars and sub...
