The stellar rotation periods of 10 exoplanet host stars have been determined using newly analysed Ca II H&K flux records from the Mount Wilson Observatory and Str¨ omgren b, y photometric measurements from Tennessee State University’s automatic photometric telescopes at the Fairborn Observatory. Five of the rotation periods have not previously been reported, with that of HD 130322 very strongly detected at Prot = 26.1 ± 3.5 d. The rotation periods of five other stars have been updated using new…

Refined Properties of the HD 130322 Planetary System
Exoplanetary systems closest to the Sun, with the brightest host stars, provide the most favorable opportunities for characterization studies of the host star and their planet(s). The Transit
A small survey of the magnetic fields of planet-host stars
Using spectropolarimetry, we investigate the large-scale magnetic topologies of stars hosting close-in exoplanets. A small survey of 10 stars has been done with the twin instruments Telescope Bernard
The transit signature of exoplanets provides an avenue through which characterization of exoplanetary properties may be undertaken, such as studies of mean density, structure, and atmospheric
Detectability of Exoplanet Periastron Passage in the Infrared
Characterization of exoplanets has matured in recent years, particularly through studies of exoplanetary atmospheres of transiting planets at infrared wavelengths. The primary source for such
Measuring rotation periods of solar-like stars using TIGRE - A study of periodic CaII H+K S-index variability
Context. The rotation period of a star is a key parameter both for the stellar dynamo that generates magnetic fields as well as for stellar differential rotation. Aims. We present the results from
Distinguishing between stellar and planetary companions with phase monitoring
Exoplanets which are detected using the radial velocity technique have a well-known ambiguity of their true mass, caused by the unknown inclination of the planetary orbit with respect to the plane of
Detecting the signatures of Uranus and Neptune
With more than 15 years since the first radial velocity discovery of a planet orbiting a Sun-like star, the time baseline for radial velocity surveys is now extending out beyond the orbit of Jupiter
On the Inclination Dependence of Exoplanet Phase Signatures
Improved photometric sensitivity from space-based telescopes has enabled the detection of phase variations for a small sample of hot Jupiters. However, exoplanets in highly eccentric orbits present
A Comprehensive Characterization of the 70 Virginis Planetary System
An on-going effort in the characterization of exoplanetary systems is the accurate determination of host star properties. This effort extends to the relatively bright host stars of planets discovered
A window on exoplanet dynamical histories: Rossiter-McLaughlin observations of WASP-13b and WASP-32b
We present Rossiter-McLaughlin observations of WASP-13b and WASP-32b and determine the sky-projected angle between the normal of the planetary orbit and the stellar rotation axis ( ). WASP-13b and


Differential Rotation of Eridani Detected by MOST
The Microvariability and Oscillations of STars (MOST) photometric satellite observed three rotations of Eri continuously in late 2005. We detected two spots (Δm ~ 0.01) at different latitudes (200,
Measurement of Spin-Orbit Alignment in an Extrasolar Planetary System
We determine the stellar, planetary, and orbital properties of the transiting planetary system HD 209458 through a joint analysis of high-precision radial velocities, photometry, and timing of the
Catalog of nearby exoplanets
We present a catalog of nearby exoplanets. It contains the 172 known low-mass companions with orbits established through radial velocity and transit measurements around stars within 200 pc. We
Searching for planets in the Hyades. III. The quest for short-period planets
We have been using the Keck I High Resolution Spectrograph to search for planetary companions in the Hyades cluster. We selected four stars from this sample that showed significant radial velocity
The Extrasolar Planet ∊ Eridani b: Orbit and Mass
Hubble Space Telescope (HST) observations of the nearby (3.22 pc) K2 V star Eridani have been combined with ground-based astrometric and radial velocity data to determine the mass of its known
No planet for HD 166435
The G0 V star HD 166435 has been observed by the ber-fed spectrograph ELODIE as one of the targets in the large extra-solar planet survey that we are conducting at the Observatory of Haute-Provence.
Planet Migration and Binary Companions: The Case of HD 80606b
The exosolar planet HD 80606b has a highly eccentric (e = 0.93) and tight (a = 0.47 AU) orbit. We study how it might arrive at such an orbit and how it has avoided being tidally circularized until
A False Planet around HD 192263
We present new high-precision Stromgren photometry and Ca II H and K spectrophotometry of HD 192263. Based on radial velocity variations detected previously by two groups, this K2 V star was thought
Orbital migration of the planetary companion of 51 Pegasi to its present location
THE recent discovery1 and confirmation2 of a possible planetary companion orbiting the solar-type star 51 Pegasi represent a breakthrough in the search for extrasolar planetary systems. Analysis of
An extrasolar planetary system with three Neptune-mass planets
Simulations show that the system of three Neptune-mass planets orbiting the nearby star HD 69830 is in a dynamically stable configuration and theoretical calculations favour a mainly rocky composition for both inner planets, while the outer planet probably has a significant gaseous envelope surrounding its rocky/icy core.
