The recent discovery of a planetary transit in the star HD 209458, and the subsequent highly precise observation of the transit light curve with Hubble Space Telescope, is encouraging to search for any phenomena that might induce small changes in the light curve. Here we consider the effect of the quadrupole moment of the parent star and of a possible second planet perturbing the orbit of the transiting planet. Both of these cause a precession of the orbital plane and of the periastron of the… 

Kepler-9: A System of Multiple Planets Transiting a Sun-Like Star, Confirmed by Timing Variations

Two Saturn-size planets show variations in the times they take to transit their star due to gravitational interaction, and six radial-velocity observations show that these two planets are the most massive objects orbiting close to the star and substantially improve the estimates of their masses.

A Dynamical Method for Measuring the Masses of Stars with Transiting Planets

As a planet transits the face of a star, it accelerates along the line of sight. The changing delay in the propagation of photons produces an apparent deceleration of the planet across the sky

The Detection and Characterization of a Nontransiting Planet by Transit Timing Variations

A planetary system with two confirmed planets and one candidate planet discovered with the publicly available data for KOI-872, reminiscent of the orderly arrangement within the solar system, with nearly coplanar and circular orbits.

On detecting terrestrial planets with timing of giant planet transits

The transits of a distant star by a planet on a Keplerian orbit occur at time intervals exactly equal to the orbital period. If a second planet orbits the same star, the orbits are not Keplerian and

Detecting New Planets in Transiting Systems

I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally

A closely packed system of low-mass, low-density planets transiting Kepler-11

Kepler spacecraft observations of a single Sun-like star are reported that reveal six transiting planets, five with orbital periods between 10 and 47 days and a sixth planet with a longer period, among the smallest for which mass and size have both been measured.

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

Using long-term transit timing to detect terrestrial planets

ABSTRACT We propose that the presence of additional planets in extrasolar planetary systemscan be detected by long-term transit timing studies. If a transiting planet is on aneccentric orbit then the

Transits in Multiple Planet Systems

Surveys for transiting extrasolar planets, including the space-based missions CoRoT and Kepler, are expected to detect hundreds of Jovian mass planets and tens of terrestrial mass planets. For many

On the detection of (habitable) super-Earths around low-mass stars using Kepler and transit timing variation method

We present the results of an extensive study of the detectability of Earth-sized planets and super-Earths in the habitable zones of cool and low-mass stars using transit timing variation method. We

Detection of Planetary Transits Across a Sun-like Star

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.

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 lifetime

We have observed four transits of the planet of HD 209458 using the STIS spectrograph on the Hubble Space Telescope (HST). Summing the recorded counts over wavelength between 582 and 638 nm yields a
