VizieR Online Data Catalog: Photometry and spectroscopy of HAT-P-57 (Hartman+, 2015)

The star HAT-P-57 was observed by the HATNet wide-field photometric instruments between the nights of UT 2009 May 12 and UT 2009 September 14. A total of 622 observations of a 10.6°*10.6° field centered at RA=06^h24^m, decl.=+30° were made with the HAT-5 telescope in Arizona, and 3202 observations of this same field were made with the HAT-9 telescope in Hawaii. We used a Sloan r filter.

Photometric follow-up observations of HAT-P-57 were carried out with KeplerCam on the Fred Lawrence Whipple Observatory (FLWO) 1.2m telescope. We observed ingress events on the nights of 2010 April 3 and 2012 April 24, in i and g-bands respectively, and a full transit on the night of 2010 June 26 in z-band. Additional photometric follow-up observations were carried out with the FLWO 1.2m on the night of 2015 May 12.

All time-series photometric data that we collected for HAT-P-57 are provided in Table1.

Spectroscopic observations were obtained using the HIgh-Resolution Echelle Spectrometer (HIRES) on the Keck-I 10m telescope between UT 2010 June 27 and UT 2012 March 10. A total of 24 HIRES observations were collected during this time period, including 14 observations made through the I₂ cell (e.g., Marcy & Butler, 1992PASP..104..270M), and 10 observations without the I₂ cell. These latter observations were obtained on the night of UT 2010 June 27, primarily during a planetary transit (Section 3.3 discusses the analysis of these observations in more detail).

Table2 gives the relative radial velocity measurements obtained with the I₂ Doppler pipeline, the radial velocity measurements obtained from the CCFs, and the Bisector Spans for the HIRES observations.
