HD 209458 planetary transits from Hipparcos photometry

, 2000
During its 39-month mission, Hipparcos observed the star HD 209458 on 89 occasions. Five of these observations are shown to correspond to epochs of planetary transits, with a 2.3±0.4% mean decrease of flux in the Hpband being observed during the transits.

GJ 238 b: A 0.57 Earth Radius Planet Orbiting an M2.5 Dwarf Star at 15.2 pc

The Astronomical Journal
We report the discovery of the transiting planet GJ 238 b, with a radius of 0.566 ± 0.014 R _⊕ (1.064 ± 0.026 times the radius of Mars) and an orbital period of 1.74 days. The transit signal was detected by the TESS mission and designated TOI-486.01. The

Concealing Circumbinary Planets with Tidal Shrinkage

The Astrophysical Journal
Of the 14 transiting planets that have been detected orbiting eclipsing binaries (“circumbinary planets”), none have been detected with stellar binary orbital periods shorter than 7 days, despite such binaries existing in abundance.

A JWST Transit of a Jupiter Analog. I. Constraints on the Oblateness of Kepler-167 e

The Astronomical Journal
In 2024 October, JWST observed a transit of Kepler-167 e, a Jupiter-analog planet on a 1000+ day orbit. These observations, recorded over a long baseline of nearly 60 hr, were designed to search for signatures of planetary oblateness and/or exomoons ...

TOI-6695: A Pair of Near-resonant Massive Planets Observed with TESS from the WINE Survey

The Astronomical Journal
We present the discovery and characterization of a pair of warm Jovian-mass exoplanets orbiting the Sun-like star TOI-6695, based on Transiting Exoplanet Survey Satellite (TESS) transits and precise radial velocity (RV) measurements obtained with FEROS ...

Validation of TESS Planet Candidates with Multicolor Transit Photometry and TRICERATOPS+

The Astronomical Journal
We present an upgraded version of TRICERATOPS , a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Survey Satellite (TESS).

Pushing the precision limit of ground-based eclipse photometry [PDF]

, 2008
Until recently, it was considered by many that ground-based photometry could not reach the high cadence sub-mmag regime because of the presence of the atmosphere.

TOI-4504: Exceptionally Large Transit Timing Variations Induced by Two Resonant Warm Gas Giants in a Three-planet System

The Astrophysical Journal Letters
We present a joint analysis of transit timing variations (TTVs) and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known TTVs, with a peak-to-node amplitude of ∼2 days, the ...

A Transiting Giant on a 7.7 yr Orbit Revealed by Transit Timing Variations in the TOI-201 System

The Astrophysical Journal Letters
We report the detection and characterization of TOI-201 c, a long-period transiting companion to the warm Jupiter TOI-201 b. Its presence was first inferred from high-amplitude transit timing variations (TTVs) in TOI-201 b, pointing to a massive outer ...
