Appearance of the broad emission lines in the optical spectrum of the black hole transient Swift J1753.5-0127
Abstract
We report the appearance of the broad emission lines in the previously featureless optical spectrum of the black hole transient Swift J1753.5-0127. The spectra of Swift J1753.5-0127 were obtained during four consecutive nights of August 6-9, 2013 at the Observatorio Astronomico Nacional (OAN SPM) in Mexico on the 2.1-m telescope with the Boller & Chivens spectrograph. A total of 54 spectra were obtained in the wavelength range of 3600-7000 A, in the first order of a 400 line/mm grating with corresponding spectral resolutions of about 3.4 A.
