VizieR Online Data Catalog: TESS light curve & radial velocities for HD 1397 (Brahm+, 2019)
Abstract
Between 2018 July 25 and 2018 August 22, the TESS mission observed HD 1397 (TIC 394137592, TOI00120.01) with its Camera 3 during the monitoring of the first TESS sector. Observations were performed with a cadence of 2 minutes. HD 1397 was also observed during the monitoring of the second TESS sector. However, no two-minute cadence light curve was processed by the SPOC pipeline. The reason for this could be related to the position of the star in the TESS detector, because it was located just a few pixels from the edge. Nonetheless, we extracted a light curve from the full-frame images (FFIs) using tesseract (http://github.com/astrofelipe/tesseract) (F. Rojas et al. 2019 in preparation). We started the radial velocity follow-up of HD 1397 a couple of hours after the first alerts of TESS Sector 1 were made public. We obtained two spectra with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph (Mayor et al. 2003Msngr.114...20M) installed at the ESO 3.6 m telescope at La Silla Observatory on two consecutive nights. Additionally, we obtained 35 spectra with the The Fiber Dual Echelle Optical Spectrograph (FIDEOS; Vanzi et al. 2018MNRAS.477.5041V) installed at the 1 m telescope on the same observatory. FIDEOS observations were obtained on six consecutive nights. We then proceeded to perform an intensive radial velocity monitoring of HD 1397 with the Fiber-fed Extended Range Optical Spectrograph (FEROS) installed at the MPG 2.2 m telescope at La Silla Observatory (Kaufer et al. 1999Msngr..95....8K). We obtained 88 spectra on a time span of 80 nights.
