It is well-known that the light curve of a transiting planet contains information about the planet's orbital period and size relative to the host star. More recently, it has been demonstrated that a tight constraint on an individual planet's eccentricity can sometimes be derived from the light curve via the "photoeccentric effect," the effect of a planet's eccentricity on the shape and duration of its light curve. This has only been studied for large planets and high signal-to-noise scenarios… Expand

Eccentricity from transit photometry: small planets in Kepler multi-planet systems have low eccentricities
Solar system planets move on almost circular orbits. In strong contrast, many massive gas giant exoplanets travel on highly elliptical orbits, whereas the shape of the orbits of smaller, moreExpand
A pilot investigation to constrain the presence of ring systems around transiting exoplanets
Abstract We demonstrate a process by which to evaluate the presence of large, Saturn-like ring systems around transiting extrasolar giant planets. We use extrasolar planet candidate KOI-422.01 as anExpand
Consequences of tidal interaction between disks and orbiting protoplanets for the evolution of multi-planet systems with architecture resembling that of Kepler 444
We study orbital evolution of multi-planet systems with masses in the terrestrial planet regime induced through tidal interaction with a protoplanetary disk assuming that this is the dominantExpand
Exoplanet orbital eccentricities derived from LAMOST–Kepler analysis
The eccentricity distributions of an unprecedented large and homogeneous sample of 698 Kepler planets are derived and a dichotomy in eccentricities is discovered: the systems with single transiting planets, which make up half of the sample, have a large mean eccentricity, whereas the multiples are on nearly circular orbits.

Long-period exoplanets from photometric transit surveys
The Bayesian transit-fitting tool ("Namaste: An MCMC Analysis of Single Transit Exoplanets") was developed to extract planetary and orbital information from single transits, and was applied to 71 candidate events detected in K2 photometry, which helped to characterise large numbers of long period planets in this way.

Spin-Orbit Misalignment of Two-Planet-System KOI-89 Via Gravity Darkening
We constrain the true spin-orbit alignment of the KOI-89 system by numerically fitting the two \emph{Kepler} photometric lightcurves produced by transiting planets KOI-89.01 and KOI-89.02. The twoExpand
Single transit candidates from K2: detection and period estimation
Photometric surveys such as Kepler have the precision to identify exoplanet and eclipsing binary candidates from only a single transit. K2, with its 75 d campaign duration, is ideally suited toExpand
The Chandra Deep Fields: Lifting the Veil on Distant Active Galactic Nuclei and X-Ray Emitting Galaxies
The Chandra Deep Fields (CDFs), being a major thrust among extragalactic X-ray surveys and complemented effectively by multiwavelength observations, have critically contributed to our dramaticallyExpand
Stability constrained characterization of multiplanet systems
Many discovered multiplanet systems are tightly packed. This implies that wide parameter ranges in masses and orbital elements can be dynamically unstable and ruled out. We present a case study ofExpand


The Photoeccentric Effect and Proto-Hot-Jupiters I. Measuring photometric eccentricities of individual transiting planets
Exoplanet orbital eccentricities offer valuable clues about the history of planetary systems. Eccentric, Jupiter-sized planets are particularly interesting: they may link the "cold" Jupiters beyondExpand
A Unique Solution of Planet and Star Parameters from an Extrasolar Planet Transit Light Curve
There is a unique solution of the planet and star parameters from a planet transit light curve with two or more transits if the planet has a circular orbit and the light curve is observed in aExpand
Transit Light Curves with Finite Integration Time: Fisher Information Analysis
Kepler has revolutionized the study of transiting planets with its unprecedented photometric precision on more than 150,000 target stars. Most of the transiting planet candidates detected by KeplerExpand
A rocky composition for an Earth-sized exoplanet
Doppler spectroscopic measurements of the mass of the Earth-sized planet Kepler-78b are reported, which is similar to Earth’s, suggesting a composition of rock and iron. Expand
On the Period Distribution of Close-in Extrasolar Giant Planets
Transit (TR) surveys for extrasolar planets have recently uncovered a population of "very hot Jupiters," planets with orbital periods of P ≤ 3 days. At first sight this may seem surprising, givenExpand
Characterizing the Orbital Eccentricities of Transiting Extrasolar Planets with Photometric Observations
The discovery of over 200 extrasolar planets with the radial velocity (RV) technique has revealed that many giant planets have large eccentricities, in striking contrast with most of the planets inExpand
An Earth-sized planet with an Earth-like density
The planet Kepler-78b was discovered and found to have a radius of only 1.16, and the mass of this planet is 1.86 Earth masses, which implies a composition of iron and rock similar to that of the Earth. Expand
Doppler planet searches have discovered that giant planets follow orbits with a wide range of orbital eccentricities, revolutionizing theories of planet formation. The discovery of hundreds ofExpand

Impact of Orbital Eccentricity on the Detection of Transiting Extrasolar Planets
For extrasolar planets with orbital periods P > 10 days, radial velocity surveys find noncircular orbital eccentricities are common, e ~ 0.3. Future surveys for extrasolar planets using the transitExpand
