New 3-D gas density maps of NaI and CaII interstellar absorption within 300pc
Barry Y. Welsh, Rosine Lallement, Jean-Luc Vergely +1
We present new high resolution (R>50,000) absorption measurements of the NaI doublet (5889 - 5895A) along 482 nearby sight-lines, in addition to 807 new measurements of the CaII K…
The thermal emission of the young and massive planet CoRoT-2b at 4.5 and 8 microns
M. Gillon, A. A. Lanotte, T. Barman +16
We report measurements of the thermal emission of the young and massive planet CoRoT-2b at 4.5 and 8 microns with the Spitzer Infrared Array Camera (IRAC). Our measured occultation…
Transit timing analysis of CoRoT-1b
Sz. Csizmadia, S. Renner, P. Barge +33
CoRoT, the pioneer space-based transit search, steadily provides thousands of high-precision light curves with continuous time sampling over periods of up to 5 months. The transits…
Intrinsic effects of the boundary condition on switching processes in spin-crossover solids
Masamichi Nishino, Cristian Enachescu, Seiji Miyashita +2
We investigated domain growth in switching processes between the low-spin and high-spin phases in thermally induced hysteresis loops of spin-crossover (SC) solids. Elastic interact…
Rate and nature of false positives in the CoRoT exoplanet search
J. M. Almenara, H. J. Deeg
Context. The CoRoT satellite searches for planets by applying the transit method, monitoring up to 12 000 stars in the galactic plane for 150 days in each observation run. This sea…
Transiting exoplanets from the CoRoT space mission VIII. CoRoT-7b: the first Super-Earth with measured radius
A. Leger, D. Rouan, J. Schneider +51
We report the discovery of very shallow (DF/F = 3.4 10-4), periodic dips in the light curve of an active V = 11.7 G9V star observed by the CoRoT satellite, which we interpret as du…
