VizieR Online Data Catalog: Mdwarfs Ha luminosity & photometric amplitudes (Garcia Soto+, 2023)
Abstract
TESS data products include 30minute cadence full frame images and 2minute cadence "postage stamp" images of selected stars. The Science Processing Operations Center produces 2minute cadence light curves FITS files, which are then released to the public via Mikulski Archive for Space Telescopes archive. We observe Hα emission using (Ohio State Multi-Object Spectrograph) OSMOS, mounted on the 2.4m Hiltner telescope at MDM Observatory in Arizona. Our setup consists of the blue VPH grism with a inner 1.2" slit and a 4x1k region of interest. The resulting spectra span 390-680nm, with peak efficiency around 640nm and a R~600 resolution. In this configuration, OSMOS is well-suited to single-object spectroscopy, particularly for our study of Hα emission at around 656.21nm.
