VizieR Online Data Catalog: IRD and HPF spectra of TRAPPIST-1b,e and f (Krishnamurthy+, 2021)

We observed a photometric transit of TRAPPIST-1b on the night of UT 2020 September 5 using the Astrophysical Research Consortium Telescope Imaging Camera (ARCTIC) on the 3.5m Astrophysical Research Consortium Telescope at Apache Point Observatory. We adopted the SDSS filter using an exposure time of 18s in the 4x4 binning fast-readout mode.

We observed the transit of TRAPPIST-1b on the night of UT 2020 September 17 using Infrared Doppler (IRD), which has a spectral resolution of ~70000 in the operating wavelength range of 0.95-1.75μm, mounted on the 8.2m Subaru Telescope on Maunakea, Hawaii.

Habitable Planet Finder (HPF) is a fiber-fed high-resolution (R=55000) spectrograph on the 10m Hobby-Eberly Telescope (HET) at McDonald Observatory in Texas. Using HPF, we obtained three transits on the nights of UT 2018 October 2, 2019 July 31, and 2020 September 5.
