Measuring Potassium in Exoplanet Atmospheres with the OSIRIS Tunable Filter
We report observations of the exoplanet host-star HD 80606 using the OSIRIS tunable filter imager. Very-high-precision, narrow-band photometry in four...
Measuring Radial Velocities in R-band with Telluric Line Calibration
The iodine gas cell is replaced by the telluric O2 and water vapor lines to calibrate observations of RV stable M dwarfs made with the High Resolution...
Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to...
Measuring stellar long surface rotation periods by combining multi-sector/cycle long-cadence data from TESS
The evolution of surface magnetic features on stars, such as spots and faculae, produces modulations in light curves. These modulations allow us to measure the...
Measuring the chemical composition of cosmic rays with AMS
AMS (Alpha Magnetic Spectrometer) is a particle detector designed to operate at the International Space Station. Starting in 2008, its purpose is to perform...
Measuring The Distances, Masses, and Radii of Neutron Stars In X-ray Binaries
Low mass X-ray binaries that have independent distance measurements and show thermonuclear X-ray bursts are ideal sources for constraining the equation of state...
Measuring the Magnetic Vector with the He I 10830 Å Line: A Rich New World
The triplet of the He I transitions around 10830 Å not only shows a rich variety of Stokes profiles, but also allows the full magnetic vector in the upper...
Measuring the Masses of the TOI-700 Planets with ESPRESSO
Over the past three decades, astronomers have discovered that small, rocky planets in temperate orbits are common around our neighboring stars. Whether or not...
