We investigate whether rings around extrasolar planets could be detected from those planets' transit light curves. To this end, we develop a basic theoretical framework for calculating and interpreting the light curves of ringed planet transits on the basis of the existing framework used for stellar occultations, a technique that has been effective for discovering and probing ring systems in the solar system. We find that the detectability of large Saturn-like ring systems is largest during… Expand

Detecting transit signatures of exoplanetary rings using SOAP3.0
CONTEXT. It is theoretically possible for rings to have formed around extrasolar planets in a similar way to that in which they formed around the giant planets in our solar system. However, no suchExpand
A Search for Ringed Exoplanets using Kepler Photometry
Models are developed to simulate lightcurves of stars dimmed by transiting exoplanets with and without rings. These models are then applied to \textit{Kepler} photometry to search for planetary ringsExpand
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
PREDICTING PHOTOMETRIC AND SPECTROSCOPIC SIGNATURES OF RINGS AROUND TRANSITING EXTRASOLAR PLANETS
We present theoretical predictions for the photometric and spectroscopic signatures of rings around transiting extrasolar planets. On the basis of a general formulation for the transiting signatureExpand
Toward Detection of Exoplanetary Rings via Transit Photometry: Methodology and a Possible Candidate
The detection of a planetary ring of exoplanets remains one of the most attractive, but challenging, goals in the field of exoplanetary science. We present a methodology that implements a systematicExpand
DETECTING THE WIND-DRIVEN SHAPES OF EXTRASOLAR GIANT PLANETS FROM TRANSIT PHOTOMETRY
Several processes can cause the shape of an extrasolar giant planet's shadow, as viewed in transit, to depart from circular. In addition to rotational effects, cloud formation, non-homogenous hazeExpand
Phase Light Curves for Extrasolar Jupiters and Saturns
We predict how a remote observer would see the brightness variations of giant planets similar to those in our solar system as they orbit their central stars. Our models are the first to use measuredExpand
On the Detection of Extrasolar Moons and Rings
Since the discovery of a planet transiting its host star in the year 2000, thousands of additional exoplanets and exoplanet candidates have been detected, mostly by NASA's Kepler space telescope.Expand
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 equallyExpand
Warm Saturns: On the Nature of Rings around Extrasolar Planets That Reside inside the Ice Line
We discuss the nature of rings that may exist around extrasolar planets. Taking the general properties of rings around the gas giants in the solar system, we infer the likely properties of ringsExpand

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
Probing Structures of Distant Extrasolar Planets with Microlensing
Planetary companions to the source stars of a caustic-crossing binary microlensing events can be detected via the deviation from the parent light curves created when the caustic magnifies theExpand
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.
