Stable fiber-illumination for extremely precise radial velocities with NEID

Shubham Kanodia, Andrea S. J. Lin, Emily Lubar +24

NEID is a high-resolution red-optical precision radial velocity (RV) spectrograph recently commissioned at the WIYN 3.5 m telescope at Kitt Peak National Observatory, Arizona, USA.…

An extreme test case for planet formation: a close-in Neptune orbiting an ultracool star

Gudmundur Stefansson, Suvrath Mahadevan, Yamila Miguel +27

In current theories of planet formation, close-orbiting planets as massive as Neptune are expected to be very rare around low-mass stars. We report the discovery of a Neptune-mass…

A hot Mars-sized exoplanet transiting an M dwarf

Caleb I. Cañas, Suvrath Mahadevan, William D. Cochran +21

We validate the planetary nature of an ultra-short period planet orbiting the M dwarf KOI-4777. We use a combination of space-based photometry from Kepler, high-precision, near-inf…

Gaia 20eae: A newly discovered episodically accreting young star

Arpan Ghosh, Saurabh Sharma, Joe. P. Ninan +18

The Gaia Alert System issued an alert on 2020 August 28, on Gaia 20eae when its light curve showed a 4.25 magnitude outburst. We present multi-wavelength photometric and spec…

Proxima Centauri as a Benchmark for Stellar Activity Indicators in the Near Infrared

Paul Robertson, Chad Bender, Suvrath Mahadevan +2

A new generation of dedicated Doppler spectrographs will attempt to detect low-mass exoplanets around mid-late M stars at near infrared (NIR) wavelengths, where those stars are bri…

Suppression of Fiber Modal Noise Induced Radial Velocity Errors for Bright Emission-Line Calibration Sources

Suvrath Mahadevan, Samuel Halverson, Lawrence Ramsey +1

Modal noise in optical fibers imposes limits on the signal to noise and velocity precision achievable with the next generation of astronomical spectrographs. This is an increasingl…
