Spectroscopic and photometric analysis of the early-type spectroscopic binary HD 161853 in the centre of an H II region

Aims. We study the O-type star HD 161853, which has been noted as a probable double-lined spectroscopic binary system. Methods. We secured high-resolution spectra of HD 161853 during the past nine years. We separated the two components in the system and measured their respective radial velocities...
