Original Research By Young Twinkle Students (ORBYTS): Ephemeris Refinement of Transiting Exoplanets III

TL;DR

This study presents photometric follow-up observations of thirteen exoplanets to refine their ephemerides, aiding future atmospheric studies and transit timing predictions, as part of a student-led research program using ground-based telescopes.

Contribution

It provides updated transit data for thirteen exoplanets, enhancing transit timing precision and supporting atmospheric characterization efforts, through a student-led observational campaign.

Findings

Refined transit timings for 13 exoplanets.

Improved ephemeris accuracy for future observations.

Demonstrated student involvement in impactful astronomical research.

Abstract

We report photometric follow-up observations of thirteen exoplanets (HATS-1 b, HATS2 b, HATS-3 b, HAT-P-18 b, HAT-P-27 b, HAT-P-30 b, HAT-P-55 b, KELT-4A b, WASP-25 b, WASP-42 b, WASP-57 b, WASP-61 b and WASP-123 b), as part of the Original Research By Young Twinkle Students (ORBYTS) programme. All these planets are potentially viable targets for atmospheric characterisation and our data, which were taken using the LCOGT network of ground-based telescopes, will be combined with observations from other users of ExoClock to ensure that the transit times of these planets continue to be well-known, far into the future.
