The GTC exoplanet transit spectroscopy survey II: An overly-large Rayleigh-like feature for exoplanet TrES-3b
Hannu Parviainen, Enric Pallé, Lisa Nortmann +4
We set to search for Rayleigh scattering and K and Na absorption signatures from the atmosphere of TrES-3b using ground-based transmission spectroscopy covering the wavelength rang…
K2-31b, a grazing transiting hot Jupiter on an 1.26-day orbit around a bright G7V star
S. Grziwa, D. Gandolfi, Sz. Csizmadia +25
We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HA…
Transiting exoplanets from the CoRoT space mission XXVIII. CoRoT-33b, an object in the brown dwarf desert with 2:3 commensurability with its host star
Sz. Csizmadia, A. Hatzes, D. Gandolfi +32
We report the detection of a rare transiting brown dwarf with a mass of 59 M_Jup and radius of 1.1 R_Jup around the metal-rich, [Fe/H] = +0.44, G9V star CoRoT-33. The orbit is ecce…
Exoplanet Transmission Spectroscopy using KMOS
Hannu Parviainen, Suzanne Aigrain, Niranjan Thatte +3
KMOS (K-Band Multi Object Spectrograph) is a novel integral field spectrograph installed in the VLT's ANTU unit. The instrument offers an ability to observe 24 2.8"2.8" sub…
LDTk: Limb Darkening Toolkit
Hannu Parviainen, Suzanne Aigrain
We present a Python package LDTk that automates the calculation of custom stellar limb darkening (LD) profiles and model-specific limb darkening coefficients (LDC) using the librar…
PyTransit: Fast and Easy Exoplanet Transit Modelling in Python
Hannu Parviainen
We present a fast and user friendly exoplanet transit light curve modelling package PyTransit, implementing optimised versions of the Gimenéz and the Mandel & Agol transit models.…
Transiting exoplanets from the CoRoT space mission XXVII. CoRoT-28b, a planet orbiting an evolved star, and CoRoT-29b, a planet showing an asymmetric transit
J. Cabrera, Sz. Csizmadia, G. Montagnier +50
Context. We present the discovery of two transiting extrasolar planets by the satellite CoRoT. Aims. We aim at a characterization of the planetary bulk parameters, which allow us t…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
