VizieR Online Data Catalog: Observations of binary stars with the DSSI. IX. (Horch+, 2020)
Abstract
The speckle observations presented here were taken on several runs beginning in 2015-March and ending in 2017-May using the Differential Speckle Survey Instrument (DSSI) at Lowell Observatory's Discovery Channel Telescope (LDT, formerly DCT).
Further spectroscopic observations were obtained in 2012-October with the Kitt Peak National Observatory (KPNO) 0.9m auxillary coude feed telescope and the coude spectrograph. YSC 127 and YSC 135 have been reobserved and seven KPNO observations obtained with various combinations of KPNO telescopes and instruments are listed in Table 2. The spectra have resolving powers that range from 16500 to 72000. An extensive number of additional observations were acquired from 2015 through 2019-April at Fairborn Observatory in southeast Arizona. During that period, we obtained 68 spectra of YSC127 and 39 spectra of YSC135 with the Tennessee State University 2m Astronomical Spectroscopic Telescope (AST) and a fiber-fed echelle spectrograph. The AST spectra (coverage of 3800-8600Å) have a resolving power of 25000 at 6000Å and signal-to-noise ratios of about 85 for YSC127 and 100 for YSC135. (6 data files).- Publication:
