Mauna Kea High Speed Photometry of Transits of the Extrasolar Planet HD 209458B

Open Astronomy, 2003
Using high-speed photometry techniques, three transits of the extrasolar planet across the disk of the star HD 209458 have been observed. The combination of a WET-style 3-channel photometer and an excellent site yielded millimagnitude photometric ...

Kepler Bonus: Light Curves of Kepler Background Sources

The Astronomical Journal, 2023
NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...

TOI-4600 b and c: Two Long-period Giant Planets Orbiting an Early K Dwarf

The Astrophysical Journal Letters, 2023
We report the discovery and validation of two long-period giant exoplanets orbiting the early K dwarf TOI-4600 ( V = 12.6, T = 11.9), first detected using observations from the Transiting Exoplanet Survey Satellite (TESS) by the TESS Single Transit ...

TOI-5205b: A Short-period Jovian Planet Transiting a Mid-M Dwarf

The Astronomical Journal, 2023
We present the discovery of TOI-5205b, a transiting Jovian planet orbiting a solar metallicity M4V star, which was discovered using Transiting Exoplanet Survey Satellite photometry and then confirmed using a combination of precise radial velocities ...

Transit Depth Variations Reveal TOI-216 b to be a Super-puff

The Astronomical Journal, 2023
The planets of the TOI-216 system have been previously observed to exhibit large transit-timing variations, which enabled precise mass characterization of both transiting planets.

Transit Analysis Package: An IDL Graphical User Interface for Exoplanet Transit Photometry

Advances in Astronomy, 2012
We present an IDL graphical user-interface-driven software package designed for the analysis of exoplanet transit light curves. The Transit Analysis Package (TAP) software uses Markov Chain Monte Carlo (MCMC) techniques to fit light curves using the ...
