TrES-1 b: A Case Study in Detecting Secular Evolution of Exoplanet Orbits

Simone R. Hagey, Billy Edwards, Angelos Tsiaras, Aaron C. Boley et autres

Abstract We present a comprehensive analysis of transit, eclipse, and radial velocity data of the hot Jupiter TrES-1 b and confirm evidence of orbital variations on secular timescales. Apparent variations due to systemic motion and light travel time effects have been ruled …

Star-spot activity, orbital obliquity, transmission spectrum, physical properties, and TTVs of the HATS-2 planetary system

Francesco Biagiotti, Luigi Mancini, John H. Southworth, J. Tregloan-Reed et autres

Our aim in this paper is to refine the orbital and physical parameters of the HATS-2 planetary system and study transit timing variations and atmospheric composition thanks to transit observations that span more than ten years and that were collected using different …

Ephemeris Updates For Seven Selected HATNet Survey Transiting Exoplanets

Atila Poro, Farzaneh Ahangarani Farahani, E. Jahangiri, A. Sarostad et autres

We refined the ephemeris of seven transiting exoplanets HAT-P-6b, HAT-P-12b, HAT-P-18b, HAT-P-22b, HAT-P-32b, HAT-P-33b, and HAT-P-52b. We observed 11 transits from eight observatories in different filters for HAT-P-6b and HAT-P-32b. Also, the Exoplanet Transit Database (ETD) observations for each of the seven …

Utilizing a Global Network of Telescopes to Update the Ephemeris for the Highly Eccentric Planet HD 80606 b and to Ensure the Efficient Scheduling of JWST

Kyle A. Pearson, Charles Beichman, Benjamin J. Fulton, Thomas M. Esposito et autres

Abstract The transiting planet HD 80606 b undergoes a 1000 fold increase in insolation during its 111 days orbit due to it being highly eccentric (e = 0.93). The planet’s effective temperature increases from 400 to over 1400 K in a few …

Kyle A. Pearson, C. A. Beichman, Benjamin J. Fulton, Thomas M. Esposito et autres

The transiting planet HD80606b undergoes a 1000-fold increase in insolation during its 111-day orbit due to it being highly eccentric (e=0.93). The planet's effective temperature increases from 400K to over 1400K in a few hours as it makes a rapid passage to …

A search for transit timing variations in the HATS-18 planetary system

John H. Southworth, Adrian J. Barker, T. C. Hinse, Y. Jongen et autres

ABSTRACT HATS-18 b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We present extensive photometry of HATS-18 from which we …
