Demonstrating high-precision photometry with a CubeSat: ASTERIA observations of 55 Cancri e [PDF]

, 2020
ASTERIA (Arcsecond Space Telescope Enabling Research In Astrophysics) is a 6U CubeSat space telescope (10 cm x 20 cm x 30 cm, 10 kg). ASTERIA's primary mission objective was demonstrating two key technologies for reducing systematic noise in photometric ...

Exoplanet Detection Using AI in Transit Photometry

, 2023
This study delves into the techniques and results of detecting exoplanets using transit photometry, leveraging data obtained from the Kepler Space Telescope. The research aims to shed light on both manual and automated approaches to exoplanet detection, with a specific emphasis on employing the folding technique to identify recurring patterns in light ...

Precision Near-Infrared Photometry for Exoplanet Transit Observations. I. Ensemble Spot Photometry for an All-Sky Survey [PDF]

Publications of the Astronomical Society of the Pacific, 2012
Near-IR observations are important for the detection and characterization of exoplanets using the transit technique, either in surveys of large numbers of stars or for follow-up spectroscopic observations of individual planets. In a controlled laboratory experiment, we imaged $\sim 10^4$ critically sampled spots onto an Teledyne Hawaii-2RG (H2RG ...

Precise Photometry and Spectroscopy of Transits

, 2007
A planetary transit produces both a photometric signal and a spectroscopic signal. Precise observations of the transit light curve reveal the planetary radius and allow a search for timing anomalies caused by satellites or additional planets. Precise measurements of the stellar Doppler shift throughout a transit (the Rossiter-McLaughlin effect) place a

A Spin-Orbit Alignment for the Hot Jupiter HATS-3b [PDF]

, 2014
We have measured the alignment between the orbit of HATS-3b (a recently discovered, slightly inflated Hot Jupiter) and the spin-axis of its host star.

A transit timing analysis with combined ground- and space-based photometry [PDF]

EPJ Web of Conferences, 2015
The analysis of timing variations of transiting exoplanets allows one to discover additional planets in the system. Such bodies can be very low in mass and radius, so that they remain undetected by transit or radial velocity methods. The CoRoT satellite looks back on six years of high precision photometry of a very high number of stars.

SOPHIE velocimetry of Kepler transit candidates XVI. Tomographic measurement of the low obliquity of KOI-12b, a warm Jupiter transiting a fast rotator [PDF]

, 2015
We present the detection and characterization of the transiting warm Jupiter KOI-12b, first identified with Kepler with an orbital period of 17.86 days. We combine the analysis of Kepler photometry with Doppler spectroscopy and line-profile tomography of

Small Telescope Exoplanet Transit Surveys: XO

, 2017
The XO project aims at detecting transiting exoplanets around bright stars from the ground using small telescopes. The original configuration of XO (McCullough et al. 2005) has been changed and extended as described here.

bRing: An observatory dedicated to monitoring the $\beta$ Pictoris b Hill sphere transit [PDF]

, 2017
Aims. We describe the design and first light observations from the $\beta$ Pictoris b Ring ("bRing") project. The primary goal is to detect photometric variability from the young star $\beta$ Pictoris due to circumplanetary material surrounding the ...
