Abstract

  • The recurrent nova V745 Sco was discovered in outburst on 2014 Feb 6 (CBET #3803) and was observed by the Chandra X-ray Observatory Low-Energy (LETG) grating on 2014 February 22.52 and 23.43 UT, and by the High-Energy (HETG; HEG and MEG) gratings on February 23.59 UT. The total net exposures were 45ks and 39ks for the LETG and HETG, respectively. The LETG spectra obtained with the HRC-S detector are dominated by emission lines in the 5-15 A range, with a first order count rate of 0.29 count/s.
