Relative photometry of transiting exoplanet CoRoT-Exo-2b
, 2009 Relative CCD photometry of the extrasolar planet COROT-Exo-2b transiting in front of its parent star was carried out at the Astronomical and Geophysical Observatory of Comenius University at Modra (AGO). Physical and orbital parameters were determined and compared with the previous published data.

The Journal of Physiology, Volume 604, Issue 14, Page 6057-6079, 15 July 2026.Abstract figure legend The lateral hypothalamus (LH) is a critical controller of innate behaviours such as feeding. It is anatomically connected to specific cortical areas. We mapped these areas using a combination of retrograde tracing and anterograde optogenetic circuit mapping.

Concealing Circumbinary Planets with Tidal Shrinkage
The Astrophysical JournalOf 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 JournalIn 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 JournalWe 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 JournalWe 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).

The Astrophysical Journal LettersWe 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 LettersWe 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 ...

Searching for Transit Timing Variations in Young Transiting Systems
The Astronomical JournalThe discovery of young (4 σ ), although differences in methodology make a totally fair comparison challenging. We show that spots have a weak-to-negligible impact on our results, and similarly cannot explain the higher TTV fraction.
