Limits on Transit Timing Variations in HAT-P-6 and WASP-1

TL;DR

This study precisely measured transit times of HAT-P-6b and WASP-1b, finding no evidence of transit timing variations, thus constraining potential additional planets or orbital perturbations in these systems.

Contribution

The paper provides updated and highly precise orbital periods for HAT-P-6b and WASP-1b, with no detected transit timing variations, improving constraints on system dynamics.

Findings

Updated orbital periods with high precision

No evidence of transit timing variations

Constraints on additional planets or perturbations

Abstract

We detected the transit of HAT-P-6b at HJD 2454698.3908 +/- 0.0011 and that of WASP-1b at HJD 2454774.3448 +/- 0.0023. The updated orbital periods of the planets are 3.852992 +/- 0.000005 days (HAT-P-6b) and 2.519970 +/- 0.000003 days (WASP-1b). There is no indication of any departures from constant orbital period in these systems.
