Long-term photometry of IC 348 with the Young Exoplanet Transit Initiative network

open access: yes, 2016
We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young Exoplanet Transit Initiative (YETI) network in the Bessel R band to find ...

KEPLER-18b, c, AND d: A SYSTEM OF THREE PLANETS CONFIRMED BY TRANSIT TIMING VARIATIONS, LIGHT CURVE VALIDATION, WARM-SPITZER PHOTOMETRY, AND RADIAL VELOCITY MEASUREMENTS [PDF]

open access: yes, 2011
We report the detection of three transiting planets around a Sun-like star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from planets using a combination of ...

Observation of the full 12-hour-long transit of the exoplanet HD80606b. Warm-Spitzer photometry and SOPHIE spectroscopy [PDF]

open access: yes, 2010
We present new observations of a transit of the 111-day-period exoplanet HD80606b. Using the Spitzer Space Telescope and its IRAC camera on the post-cryogenic mission, we performed a 19-hour-long photometric observation of HD80606 that covers the full ...

Millimagnitude Optical Photometry for the Transiting Planetary Candidate OGLE‐TR‐109 [PDF]

open access: yesThe Astrophysical Journal, 2006
We present precise V-band photometry for the low-amplitude transit candidate star OGLE-TR-109. This is an extreme case among the transiting candidates found by the OGLE group because of the early spectral type of the star (F0V), of the low transit amplitude (A_I=0.008 mag), and of the very short period (P=0.58909 days) of the orbiting companion.

Exoplanet Detection Using AI in Transit Photometry

open access: yes, 2023
This study delves into the techniques and results of detecting exoplanets using transit photometry, leveraging data obtained from the Kepler Space Telescope. The research aims to shed light on both manual and automated approaches to exoplanet detection, with a specific emphasis on employing the folding technique to identify recurring patterns in light ...

Precise Photometry and Spectroscopy of Transits

open access: yes, 2007
A planetary transit produces both a photometric signal and a spectroscopic signal. Precise observations of the transit light curve reveal the planetary radius and allow a search for timing anomalies caused by satellites or additional planets. Precise measurements of the stellar Doppler shift throughout a transit (the Rossiter-McLaughlin effect) place a

A transit timing analysis with combined ground- and space-based photometry [PDF]

open access: yesEPJ Web of Conferences, 2015
The analysis of timing variations of transiting exoplanets allows one to discover additional planets in the system. Such bodies can be very low in mass and radius, so that they remain undetected by transit or radial velocity methods. The CoRoT satellite looks back on six years of high precision photometry of a very high number of stars.
