Scrambling the pupil of the Hobby Eberly Telescope

Posted on June 24, 2021 by Shubham Kanodia

Detection of small Earth like planets in the habitable-zones (HZ) of M dwarfs requires precise radial velocity measurements (RV) at the meter-per-second level. These extremely precise measurements are really hard! As the schematic below illustrates, they necessitate each step in … Continue reading →

Wavelength-dependent behavior of the HPF Fabry-Pérot

Posted on May 6, 2021 by Ryan Carl Terrien

The need for a good ruler HPF is a high-precision spectrograph; it is designed to make very precise measurements of the wavelengths of stellar spectral features, so that the subtle Doppler shifts related to any orbiting exoplanets can be detected. … Continue reading →
