An Inexpensive Field-Widened Monolithic Michelson Interferometer for Precision Radial Velocity Measurements
Suvrath Mahadevan, Jian Ge, Scott W. Fleming +4
We have constructed a thermally compensated field-widened monolithic Michelson interferometer that can be used with a medium-resolution spectrograph to measure precise Doppler radi…
Detecting "Temperate" Jupiters: The Prospects of Searching for Transiting Gas Giants in Habitability Zones
S. W. Fleming, S. R. Kane, P. R. McCullough +1
This paper investigates the effects of observing windows on detecting transiting planets by calculating the fraction of planets with a given period that have zero, one (single), tw…
Measuring Stellar Radial Velocities with a Dispersed Fixed-Delay Interferometer
Suvrath Mahadevan, Julian van Eyken, Jian Ge +5
We demonstrate the ability to measure precise stellar barycentric radial velocities with the dispersed fixed-delay interferometer technique using the Exoplanet Tracker (ET), an ins…
A Transiting Planet of a Sun-like Star
P. R. McCullough, J. E. Stys, Jeff A. Valenti +11
A planet transits an 11th magnitude, G1V star in the constellation Corona Borealis. We designate the planet XO-1b, and the star, XO-1, also known as GSC 02041-01657. XO-1 lacks a t…
The First Extrasolar Planet Discovered with a New Generation High Throughput Doppler Instrument
Jian Ge, Julian van Eyken, Suvrath Mahadevan +17
We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a you…
The XO Project: Searching for Transiting Extra-solar Planet Candidates
P. R. McCullough, J. E. Stys, J. A. Valenti +3
The XO project's first objective is to find hot Jupiters transiting bright stars, i.e. V < 12, by precision differential photometry. Two XO cameras have been operating since Septem…
