Direct imaging of long period radial velocity targets with NICI
(2013-06-30)
We are finally entering an era where radial velocity and direct imaging parameter spaces are starting to overlap. Radial velocity measurements provide us with a minimum mass for an orbiting companion (the mass as a function ...
Observing Strategies for the Detection of Jupiter Analogs
(2013-04)
To understand the frequency, and thus the formation and evolution, of planetary systems like our own solar system, it is critical to detect Jupiter-like planets in Jupiter-like orbits. For long-term radial-velocity monitoring, ...
A planetary system around the nearby M dwarf GJ 667C with at least one super-earth in its habitable zone
(2012-05-20)
We re-analyze 4 years of HARPS spectra of the nearby M1.5 dwarf GJ 667C available through the European Southern Observatory public archive. The new radial velocity (RV) measurements were obtained using a new data analysis ...
The frequency of low-mass exoplanets III. Toward eta-Earth at short periods
(2011-09)
Determining the occurrence rate of "super-Earth" planets (m sin i < 10 M ) is a critically important step on the path toward determining the frequency of Earth-like planets (η), and hence the uniqueness of our solar system. ...
The Anglo-Australian planet search XXI : a gas-giant planet in a one year orbit and the habitability of gas-giant satellites
(2011-05-01)
We have detected the Doppler signature of a gas-giant exoplanet orbiting the star HD 38283, in an eccentric orbit with a period of almost exactly one year (P = 363.2 +/- 1.6 d, m sin i = 0.34 +/- 0.02 M-Jup, e = 0.41 +/- ...
