The Breakthrough Listen Search for Intelligent Life: Detection and Characterization of Anomalous Transits in Kepler Lightcurves

The Astronomical Journal, 2023
Never before has the detection and characterization of exoplanets via transit photometry been as promising and feasible as it is now, due to the increasing breadth and sensitivity of time domain optical surveys.

Refining the Transit-timing and Photometric Analysis of TRAPPIST-1: Masses, Radii, Densities, Dynamics, and Ephemerides

The Planetary Science Journal, 2021
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST, and K2 transit-time measurements, and revisit an N -body dynamical analysis of the seven-planet system using ...

Time evolution and rotation of starspots on CoRoT-2 from the modelling of transit photometry [PDF]

, 2011
CoRoT-2, the second planet-hosting star discovered by the CoRoT satellite, is a young and active star. A total of 77 transits were observed for this system over a period of 135 days.

Photometry of exoplanetary transits at Osservatorio Polifunzionale del Chianti [PDF]

Experimental Astronomy, 2020
AbstractIn this paper we report the observations of HD189733b, Kepler-41b, Kepler-42b, GJ 436b, WASP-77ab, HAT-P-32b and EPIC 211818569 as measured at the Osservatorio Polifunzionale del Chianti, a new astro-nomical site in Italy. Commissioning observing runs have been done in order to test capabilities, systematics and limits of the system and to ...

Methods for exomoon characterization: Combining transit photometry and the Rossiter-McLaughlin effect [PDF]

, 2010
It has been suggested that moons around transiting exoplanets may cause an observable signal in transit photometry or in the Rossiter-McLaughlin (RM) effect.

High accuracy transit photometry of the planet OGLE-TR-113b with a new deconvolution-based method [PDF]

, 2006
A high accuracy photometry algorithm is needed to take full advantage of the potential of the transit method for the characterization of exoplanets, especially in deep crowded fields.

Doomed Worlds. II. Reassessing Suggestions of Orbital Decay for TrES-5 b

The Planetary Science Journal
TrES-5 b is one of only three ultrahot Jupiters with suggestions of a possibly decreasing orbital period that have persisted through multiple independent analyses.

Spitzer Transit and Secondary Eclipse Photometry of GJ 436b [PDF]

The Astrophysical Journal, 2007
We report the results of infrared (8 micron) transit and secondary eclipse photometry of the hot Neptune exoplanet, GJ436b using Spitzer. The nearly photon-limited precision of these data allow us to measure an improved radius for the planet, and to detect the secondary eclipse.
