A frozen super-Earth orbiting a star at the bottom of the Main Sequence
D. Kubas, J. P. Beaulieu, D. P. Bennett +19
We observed the microlensing event MOA-2007-BLG-192 at high angular resolution in JHKs with the NACO adaptive optics system on the VLT while the object was still amplified by a fac…
Monitoring the large-scale magnetic field of AD~Leo with SPIRou, ESPaDOnS and Narval. Toward a magnetic polarity reversal?
S. Bellotti, J. Morin, L. T. Lehmann +23
One manifestation of dynamo action on the Sun is the 22-yr magnetic cycle, exhibiting a polarity reversal and a periodic conversion between poloidal and toroidal fields. For M dwar…
ExELS: an exoplanet legacy science proposal for the ESA Euclid mission I. Cold exoplanets
M. T. Penny, E. Kerins, N. Rattenbury +11
Euclid is the second M-class mission of the ESA Cosmic Vision programme, with the principal science goal of studying dark energy. Euclid is also expected to undertake additional Le…
High resolution spectroscopy for Cepheids distance determination. V. Impact of the cross-correlation method on the p-factor and the gamma-velocities
N. Nardetto, W. Gieren, P. Kervella +5
The cross correlation method (hereafter CC) is widely used to derive the radial velocity curve of Cepheids when the signal to noise of the spectra is low. However, if it is used wi…
New neighbours: V. 35 DENIS late-M dwarfs between 10 and 30 parsecs
N. Phan-Bao, F. Crifo, X. Delfosse +7
This paper reports updated results on our systematic mining of the DENIS database for nearby very cool M-dwarfs (M6V-M8V, 2.0<I-J<3.0, photometric distance within 30 pc), We calibr…
The PLANET microlensing campaign: Implications for planets around galactic disk and bulge stars
M. Dominik, M. D. Albrow, J. -P. Beaulieu +17
With round-the-clock monitoring of galactic bulge microlensing events, the PLANET experiment constrains the abundance and can yield the discovery of planets down to the mass of ear…
