Theia: Faint objects in motion or the new astrometry frontier

A. Krone-Martins, A. Amorim, Guillem Anglada-Escudé, A. Brandeker et autres

In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint objects in the Universe. Theia is primarily designed to study the …

The PLATO 2.0 Mission

Heike Rauer, C. Catala, Conny Aerts, Thierry P. Appourchaux et autres

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addresses fundamental questions such as: How do planetary systems form and evolve? Are there other systems …

Detection of Neptune-size planetary candidates with CoRoT data

Aldo Stefano Bonomo, Pierre-Yves Chabaud, M. Deleuil, C. Moutou et autres

Context. The CoRoT space mission has been searching for transiting planets since the end of December 2006. It has led to the detection of about twenty Jupiter-size planets and three planets with radius Rp ≲ 5 R⊕. The latter are CoRoT-7b, the …

Erratum to “Could CoRoT-7b and Kepler-10b be remnants of evaporated gas or ice giants?”

M. Leitzinger, P. Odert, Yu. N. Kulikov, Helmut Lammer et autres

The authors regret that a graphical error (wrong y-axis labeling) in the lower right panel of Fig. 3 has occurred.The caption of Fig. 3 had to be corrected too, according to the arrangement of the panels.Furthermore the panels of Fig. 1 needed …

Planetary transit candidates in the CoRoT-SRc01 field

Anders Erikson, A. Santerne, S. Renner, P. Barge et autres

Context. The space mission CoRoT is devoted to the analysis of stellar variability and the photometric detection of extrasolar planets.Aims. We present the list of planetary transit candidates detected in the first short run observed by CoRoT that targeted SRc01, towards the …

Transiting exoplanets from the CoRoT space mission

Daniel Rouan, H. Parviainen, C. Moutou, M. Deleuil et autres

We report the detection of CoRoT-23b, a hot Jupiter transiting in front of its host star with a period of 3.6314 ± 0.0001 days. This planet was discovered thanks to photometric data secured with the CoRoT satellite, combined with spectroscopic radial velocity …

Transiting exoplanets from the CoRoT space mission

Guillaume Hébrard, T. M. Evans, R. Alonso, Malcolm C. Fridlund et autres

We report the detection of CoRoT-18b, a massive hot Jupiter transiting in front of its host star with a period of 1.9000693 ± 0.0000028 days. This planet was discovered thanks to photometric data secured with the CoRoT satellite combined with spectroscopic and …

Exoplanet status report: Observation, characterization and evolution of exoplanets and their host stars

H. Lammer, A. Hanslmeier, J. Schneider, И. Статева et autres

After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science during the past decade. The characterization of …

Transiting exoplanets from the CoRoT space mission

Heike Rauer, Didier P. Queloz, Sz. Csizmadia, M. Deleuil et autres

Aims. The CoRoT space mission continues to photometrically monitor about 12 000 stars in its field-of-view for a series of target fields to search for transiting extrasolar planets ever since 2007. Deep transit signals can be detected quickly in the “alarm-mode” in …

Removing systematics from the CoRoT light curves

T. Mazeh, P. Guterman, S. Aigrain, S. Zucker et autres

This paper presents an analysis that searched for systematic effects within the CoRoT exoplanet field light curves. The analysis identified a systematic effect that modified the zero point of most CoRoT exposures as a function of stellar magnitude. We could find this …
