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 ...

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 ...

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 ...

Scintillation Noise in Exoplanet Transit Photometry
Journal of Physics: Conference Series, 2015 Transit photometry is a powerful technique for studying exoplanets. Transit observations from the ground of targets of magnitude V= 10 or brighter, however, are limited by scintillation noise due to Earth's atmosphere. Through turbulence profiling using instruments such as the stereo-SCIDAR, we have shown to able to accurately model scintillation noise,

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.

Comet C/2011 J2 (LINEAR): Photometry and stellar transit [PDF]
Planetary and Space Science, 2016 We present results of two-year photometric monitoring of Comet C/2011 J2 (LINEAR) that spans the time period from February 2013 through December 2014, before and after perihelion passage. The observations were conducted with broadband R filter. Analysis of observations of Comet C/2011 J2 (LINEAR) allows estimating the nucleus radius as function of ...
