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).

transit-timing/transit-timing: Transit Timing En Masse
, 2022 This repository contains source code for the "TESS Transit Timing of 277 Planets" paper. The repository provides code (1) to process TESS light curves (with 2, 10, or 30-minute sampling) to extract transit times, and (2) to automatically download arXiv ...

Exoplanet transit spectro-photometry with SOFIA [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractWe present the prospects of observing extrasolar planets with the Stratospheric Observatory for Infrared Astronomy (SOFIA). Our analysis shows that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and\break eclipses will be feasible with SOFIA's instrumentation, especially with the ...

Transit origami: a method to coherently fold exomoon transits in time series photometry [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT One of the simplest ways to identify an exoplanetary transit is to phase fold a photometric time series upon a trial period – leading to a coherent stack when using the correct value. Such phase-folded transits have become a standard data visualization in modern transit discovery papers.

No Conclusive Evidence for Transits of Proxima b in MOST Photometry [PDF]
The Astronomical Journal, 2017 Abstract The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days. Although the a priori probability that Proxima b transits its parent star is just 1.5%, the potential impact of such a discovery would be ...

Constraining the oblateness of transiting planets with photometry and spectroscopy [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Rapid planetary rotation can cause the equilibrium shape of a planet to be oblate. While planetary oblateness has mostly been probed by examining the subtle ingress and egress features in photometric transit light curves, we investigate the effect of oblateness on the spectroscopic Rossiter–McLaughlin (RM) signals. We found that

NEAR-INFRARED TRANSIT PHOTOMETRY OF THE EXOPLANET HD 149026b [PDF]
The Astrophysical Journal, 2009 The transiting exoplanet HD 149026b is an important case for theories of planet formation and planetary structure, because the planet's relatively small size has been interpreted as evidence for a highly metal-enriched composition. We present observations of 4 transits with the Near Infrared Camera and Multi-Object Spectrometer on the Hubble Space ...

Feasibility of transit photometry of nearby debris discs [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Dust in debris discs is constantly replenished by collisions between larger objects. In this paper, we investigate a method to detect these collisions. We generate models based on recent results on the Fomalhaut debris disc, where we simulate a background star transiting behind the disc, due to the proper motion of Fomalhaut.
