Possible detection of phase changes from the non-transiting planet HD 46375b by CoRoT
P. Gaulme, M. Vannier, T. Guillot +19
The present work deals with the detection of phase changes in an exoplanetary system. HD 46375 is a solar analog known to host a non-transiting Saturn-mass exoplanet with a 3.0236…
A mid-term astrometric and photometric study of Trans-Neptunian Object (90482) Orcus
J. L. Ortiz, A. Cikota, S. Cikota +7
From CCD observations of a fixed and large star field that contained the binary TNO Orcus, we have been able to derive high-precision relative astrometry and photometry of the Orcu…
A collision in 2009 as the origin of the debris trail of asteroid P/2010 A2
Colin Snodgrass, Cecilia Tubiana, Jean-Baptiste Vincent +15
The peculiar object P/2010 A2 was discovered by the LINEAR near-Earth asteroid survey in January 2010 and given a cometary designation due to the presence of a trail of material, a…
Transiting exoplanets from the CoRoT space mission XIV. CoRoT-11b: a transiting massive "hot-Jupiter" in a prograde orbit around a rapidly rotating F-type star
D. Gandolfi, G. Hébrard, R. Alonso +52
The CoRoT exoplanet science team announces the discovery of CoRoT-11b, a fairly massive hot-Jupiter transiting a V=12.9 mag F6 dwarf star (M*=1.27 +/- 0.05 Msun, R*=1.37 +/- 0.03 R…
First results on Martian carbon monoxide from Herschel/HIFI observations
P. Hartogh, M. I. Błęcka, C. Jarchow +48
We report on the initial analysis of Herschel/HIFI carbon monoxide (CO) observations of the Martian atmosphere performed between 11 and 16 April 2010. We selected the (7-6) rotatio…
Herschel/HIFI observations of Mars: first detection of O_2 at submillimetre wavelengths and upper limits on HCl and H_2O_2
P. Hartogh, C. Jarchow, E. Lellouch +47
We report on an initial analysis of Herschel/HIFI observations of hydrogen chloride (HCl), hydrogen peroxide (H_2O_2), and molecular oxygen (O_2) in the Martian atmosphere performe…
