Doppler measurements from Keck exhibit a sinusoidal periodicity in the velocities of the G0 dwarf HD 209458, having a semiamplitude of 81 m s-1 and a period of 3.5239 days, which is indicative of a "51 Peg-like" planet with a minimum mass (Msini) of 0.62 MJup and a semimajor axis of 0.046 AU. Follow-up photometry reveals a drop of 0.017 mag at the predicted time (within the errors) of transit by the companion based on the velocities. This is the first extrasolar planet observed to transit its… Expand

Planetary Companions to the Metal-rich Stars BD –10°3166 and HD 52265*
Precise Doppler measurements from the Keck/HIRES spectrometer reveal periodic Keplerian velocity variations in the stars BD -10°3166 and HD 52265. BD -10°3166 (K0 V) has a period of 3.487 days and aExpand
TrES-1: The Transiting Planet of a Bright K0 V Star
We report the detection of a transiting Jupiter-sized planet orbiting a relatively bright (V = 11.79) K0 V star. We detected the transit light-curve signature in the course of the TrES multisiteExpand
A Neptune-Mass Planet Orbiting the Nearby M Dwarf GJ 436
We report precise Doppler measurements of GJ 436 (M2.5 V) obtained at Keck Observatory. The velocities reveal a planetary companion with orbital period of 2.644 days, eccentricity of 0.12 (consistentExpand
Transit Photometry of the Core-dominated Planet HD 149026b
We report g, V, and r photometric time series of HD 149026 spanning predicted times of transit of the Saturn-mass planetary companion, which was recently discovered by Sato and collaborators. WeExpand
HD 17156b: A Transiting Planet with a 21.2 Day Period and an Eccentric Orbit
We report the detection of transits by the 3.1MJup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sept. 9/10, 2007 (two in central Italy and oneExpand
Evolution of "51 Pegasus b-like" planets
About one-quarter of the extrasolar giant planets discovered so far have orbital distances smaller than 0.1 AU. These “51 Peg b-like” planets can now be directly characterized, as shown by the planetExpand
A Transiting Planet of a Sun-like Star
A planet transits an 11th magnitude, G1 V star in the constellation Corona Borealis. We designate the planet XO-1b and the star XO-1, also known as GSC 02041-01657. XO-1 lacks a trigonometricExpand
Three small transiting planets around the M dwarf host star LP 358-499
We report on the detection of three transiting small planets around the low-mass star LP 358-499 (K2-133), using photometric data from the Kepler-K2 mission. Using multiband photometry, we determineExpand
An extrasolar planet that transits the disk of its parent star
Planets orbiting other stars could in principle be found through the periodic dimming of starlight as a planet moves across—or ‘transits’—the line of sight between the observer and the star.Expand
THE FREQUENCY OF LARGE-RADIUS HOT AND VERY HOT JUPITERS IN ω CENTAURI
We present the results of a deep, wide-field search for transiting hot Jupiter (HJ) planets in the globular cluster ? Centauri. As a result of a 25 night observing run with the ANU 40 inch (1 m)Expand

The Planet around 51 Pegasi
Doppler measurements of 51 Pegasi have been made from 1995 October through 1996 August, with a precision of 5 m s-1. We find a period of 4.231 days, a velocity amplitude of 56 ± 1 m s-1, and aExpand
PROPERTIES OF SUN-LIKE STARS WITH PLANETS: 51 PEGASI,
Radial velocity variations have revealed planets orbiting 51 Peg, 47 UMa, and 70 Vir, and a low-mass companion orbiting HD 114762. We analyze parallel records of photometric measurements in StroŽExpand
Three New “51 Pegasi-Type” Planets*
We report Keplerian Doppler velocity variations, consistent with orbiting "51 Pegasi-type" planets, for the three stars HR 3522 (G8V), HR 5185 (F7V), and HR 458 (F8V). HR 3522 exhibits a velocityExpand
Detection of Planetary Transits Across a Sun-like Star.
TLDR
High-precision, high-cadence photometric measurements of the star HD 209458 are reported, which is known from radial velocity measurements to have a planetary-mass companion in a close orbit and the detailed shape of the transit curve due to both the limb darkening of thestar and the finite size of the planet is clearly evident.

A Planet with a 3.1 Day Period around a Solar Twin
Doppler measurements from the Keck/HIRES spectrometer of the G3 V star HD 187123 reveal Keplerian variations with a period of 3.097 days and a semiamplitude of 72 m s–1. An orbital fit yields aExpand
Giant planets at small orbital distances
Using Doppler spectroscopy to detect the reflex motion of the nearby star, 51 Pegasi, Mayor & Queloz (1995) claim to have discovered a giant planet in a 0.05 AU, 4.23 day orbit. They estimate itsExpand
Properties of Sun-like Stars with Planets: ρ1 Cancri, τ Bootis, and υ Andromedae*

A Theory of Extrasolar Giant Planets
We present a broad suite of models of extrasolar giant planets (EGP's), ranging in mass from 0.3 to 15 Jupiter masses. The models predict luminosity (both reflected and emitted) as a function of age,Expand
Tidal decay of close planetary orbits
The 4.2-day orbit of the newly discovered planet around 51~Pegasi is formally unstable to tidal dissipation. However, the orbital decay time in this system is longer than the main-sequence lifetimeExpand
