EarthFinder Probe Mission Concept Study: Characterizing nearby stellar exoplanet systems with Earth-mass analogs for future direct imaging
Peter Plavchan, Gautam Vasisht, Chas Beichman +52
EarthFinder is a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on…
Precise Radial Velocities of Cool Low Mass Stars With iSHELL
Bryson Cale, Peter Plavchan, Danny LeBrun +11
The coolest dwarf stars are intrinsically faint at visible wavelengths and exhibit rotationally modulated stellar activity from spots and plages. It is advantageous to observe thes…
Precise Near-Infrared Radial Velocities with iSHELL
Bryson Cale, Peter Plavchan, Jonathan Gagné +3
We present a possible NASA key project using the iSHELL near-infrared high-resolution echelle spectrograph on the NASA Infrared Telescope Facility for precise radial velocity follo…
EarthFinder: A Precise Radial Velocity Probe Mission Concept For the Detection of Earth-Mass Planets Orbiting Sun-like Stars
Peter Plavchan, Bryson Cale, Patrick Newman +40
EarthFinder is a Probe Mission concept selected for study by NASA for input to the 2020 astronomy decadal survey. This study is currently active and a final white paper report is d…
Retrieval of Precise Radial Velocities from Near-Infrared High Resolution Spectra of Low Mass Stars
Peter Gao, Peter Plavchan, Jonathan Gagné +21
Given that low-mass stars have intrinsically low luminosities at optical wavelengths and a propensity for stellar activity, it is advantageous for radial velocity (RV) surveys of t…
Demonstration of a Near-IR Laser Comb for Precision Radial Velocity Measurements in Astronomy
X. Yi, K. Vahala, S. Diddams +14
We describe a successful effort to produce a laser comb around 1.55 m in the astronomical H band using a method based on a line-referenced, electro-optical-modulation frequency…
