New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems

P. Bluhm, M. I. Jones, L. Vanzi +10

We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orb…

New Planetary Systems from the Calan-Hertfordshire Extrasolar Planet Search

J. S. Jenkins, H. R. A. Jones, M. Tuomi +22

We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as p…

A HARPS view on K2-3

J. M. Almenara, N. Astudillo-Defru, X. Bonfils +14

K2 space observations recently found that three super-Earths transit the nearby M dwarf K2-3. The apparent brightness and the small physical radius of their host star rank these pl…

Giant planets around two intermediate-mass evolved stars and confirmation of the planetary nature of HIP67851 c

M. I. Jones, J. S. Jenkins, P. Rojo +1

Precision radial velocities are required to discover and characterize planets orbiting nearby stars. Optical and near infrared spectra that exhibit many hundreds of absorption line…

The HARPS search for southern extra-solar planets XXXV. Planetary systems and stellar activity of the M dwarfs GJ 3293, GJ 3341, and GJ 3543

N. Astudillo-Defru, X. Bonfils, X. Delfosse +13

Context. Planetary companions of a fixed mass induce larger amplitude reflex motions around lower-mass stars, which helps make M dwarfs excellent targets for extra-solar planet sea…

A planetary system and a highly eccentric brown dwarf around the giant stars HIP67851 and HIP97233

M. I. Jones, J. S. Jenkins, P. Rojo +2

Context: So far more than 60 substellar companions have been discovered around giant stars. These systems present physical and orbital properties that contrast to those detected or…

The properties of planets around giant stars

M. I. Jones, J. S. Jenkins, P. Bluhm +2

Context: More than 50 exoplanets have been found around giant stars, revealing different properties when compared to planets orbiting solar-type stars. In particular, they are Supe…

Precision radial velocities of 15 M5 - M9 dwarfs

J. R. Barnes, J. S. Jenkins, H. R. A. Jones +8

We present radial velocity measurements of a sample of M5V-M9V stars from our Red-Optical Planet Survey, ROPS, operating at 0.65-1.025 micron. Radial velocities for 15 stars, with…

Study of the impact of the post-MS evolution of the host star on the orbits of close-in planets. II. A giant planet in a close-in orbit around the RGB star HIP63242

M. I. Jones, J. S. Jenkins, P. Rojo +2

Context: More than 40 planets have been found around giant stars, revealing a lack of systems orbiting interior to 0.6 AU. This observational fact contrasts with the planeta…

Stellar activity as a tracer of moving groups

F. Murgas, J. S. Jenkins, P. Rojo +2

We present the results of a study of the stellar activity in the solar neighborhood using complete kinematics (galactocentric velocities U,V,W) and the chromospheric activity index…

ROPS: A New Search for Habitable Earths in the Southern Sky

J. R. Barnes, J. S. Jenkins, H. R. A. Jones +7

We present the first results from our Red Optical Planet Survey (ROPS) to search for low mass planets orbiting late type dwarfs (M5.5V - M9V) in their habitable zones (HZ). Our obs…

Study of the impact of the post-MS evolution of the host star on the orbits of close-in planets. I. Sample definition and physical properties

M. I. Jones, J. S. Jenkins, P. Rojo +1

Context: To date, more than 30 planets have been discovered around giant stars, but only one of them has been found to be orbiting within 0.6 AU from the host star, in direct contr…

Near-infrared integral-field spectra of the planet/brown dwarf companion AB Pic b

M. Bonnefoy, G. Chauvin, P. Rojo +5

Chauvin et al. 2005 imaged a co-moving companion at ~260 AU from the young star AB Pic A. Evolutionary models predictions based on J H K photometry of AB Pic b suggested a mass of…
