'Modal-noise' in single-mode fibers: A cautionary note for high precision radial velocity instruments
Samuel Halverson, Arpita Roy, Suvrath Mahadevan +1
Exploring the use of single-mode fibers (SMFs) in high precision Doppler spectrometers has become increasingly attractive since the advent of diffraction-limited adaptive optics sy…
Evidence for Reflected Light from the Most Eccentric Exoplanet Known
Stephen R. Kane, Robert A. Wittenmyer, Natalie R. Hinkel +16
Planets in highly eccentric orbits form a class of objects not seen within our Solar System. The most extreme case known amongst these objects is the planet orbiting HD~20782, with…
Stellar activity mimics a habitable-zone planet around Kapteyn's star
Paul Robertson, Arpita Roy, Suvrath Mahadevan
Kapteyn's star is an old M subdwarf believed to be a member of the Galactic halo population of stars. A recent study has claimed the existence of two super-Earth planets around the…
An efficient, compact, and versatile fiber double scrambler for high precision radial velocity instruments
Samuel Halverson, Arpita Roy, Suvrath Mahadevan +5
We present the design and test results of a compact optical fiber double-scrambler for high-resolution Doppler radial velocity instruments. This device consists of a single optic:…
Response to Comment on "Stellar activity masquerading as planets in the habitable zone of the M dwarf Gliese 581"
Paul Robertson, Suvrath Mahadevan, Michael Endl +1
Anglada-Escudé and Tuomi question the statistical rigor of our analysis while ignoring the stellar activity aspects that we present. Although we agree that improvements in multipar…
The APOGEE Spectroscopic Survey of Kepler Planet Hosts: Feasibility, Efficiency, and First Results
Scott W. Fleming, Suvrath Mahadevan, Rohit Deshpande +33
The Kepler mission has yielded a large number of planet candidates from among the Kepler Objects of Interest (KOIs), but spectroscopic follow-up of these relatively faint stars is…
