Photometry of exoplanetary transits at Osservatorio Polifunzionale del Chianti [PDF]
Experimental Astronomy, 2020 AbstractIn this paper we report the observations of HD189733b, Kepler-41b, Kepler-42b, GJ 436b, WASP-77ab, HAT-P-32b and EPIC 211818569 as measured at the Osservatorio Polifunzionale del Chianti, a new astro-nomical site in Italy. Commissioning observing runs have been done in order to test capabilities, systematics and limits of the system and to ...

Linearized Field Deblending: PSF Photometry for Impatient Astronomers [PDF]
, 2021 NASA's Kepler, K2 and TESS missions employ Simple Aperture Photometry (SAP) to derive time-series photometry, where an aperture is estimated for each star, and pixels containing each star are summed to create a single light curve. This method is simple, but in crowded fields the derived time-series can be highly contaminated.

Spitzer Transit and Secondary Eclipse Photometry of GJ 436b [PDF]
The Astrophysical Journal, 2007 We report the results of infrared (8 micron) transit and secondary eclipse photometry of the hot Neptune exoplanet, GJ436b using Spitzer. The nearly photon-limited precision of these data allow us to measure an improved radius for the planet, and to detect the secondary eclipse.

MULTI-COLOR TRANSIT PHOTOMETRY OF GJ 1214b THROUGH BJHKs BANDS AND A LONG-TERM MONITORING OF THE STELLAR VARIABILITY OF GJ 1214 [PDF]
, 2013 We present five new transit light curves of GJ 1214b taken in the BJHKs bands. Two transits were observed in the B band using the Subaru Prime Focus Camera (Suprime-Cam) and the Faint Object Camera and Spectrograph (FOCAS) instruments on board the Subaru

A search for transits of GJ 581\lowercase{e} and characterization of the host star variability using MOST space telescope photometry [PDF]
, 2012 The GJ 581 system has been amply studied since its discovery in 2005: the number of known planets in the system has increased and their orbital parameters are among the most precisely determined for radial velocity detected exoplanets.
