We then implemented the radial velocities of the eclipsing binary and the light curves in the Wilson-Devinney code iteratively to derive stellar parameters for its components. Once the four radial velocities were derived, we obtained a model to fit the radial-velocity curves using the Spectroscopic Binary Orbit Program (SBOP). We have developed our own program to fit four components to the combined line shapes. We use their analysis, in combination with the photometric data from All Sky Automated Survey and H ipparcos catalogues, to conclude that HD 64315 is composed of at least two spectroscopic binaries, one of which is an eclipsing binary. A total of 52 high-resolution spectra have been gathered over a decade. We explore the multiple nature of this star with the aim of determining its distance, and understanding its connection to NGC 2467. Moreover, it has been identified as a spectroscopic binary, but existing data support contradictory values for its orbital period.Īims. The O6 Vn star HD 64315 is believed to belong to the star-forming region known as NGC 2467, but previous distance estimates do not support this association. 201, 08034 Barcelona, Spainĥ Centro de Astrobiología (CSIC/INTA), Instituto Nacional de Técnica Aeroespacial, 28850 Torrejón de Ardoz, Madrid, SpainĦ UK Astronomy Technology Centre, Royal Observatory Edinburgh, Blackford Hill, Edinburgh EH9 3HJ, UKħ Departamento de Astrofísica y Ciencias de la Atmósfera, Facultad de Ciencias Físicas, Universidad Complutense de Madrid, 28040 Madrid, SpainĬontext. de Física, Ingeniería de Sistemas y Teoría de la Señal, Escuela Politécnica Superior, Universidad de Alicante, Carretera San Vicente del Raspeig s/n, 03690 San Vicente del Raspeig, SpainĮ-mail: Departamento de Astrofísica, Universidad de La Laguna, 38205 La Laguna, Tenerife, Spainģ Instituto de Astrofísica de Canarias, 38200 La Laguna, Tenerife, SpainĤ Institut d’Estudis Espacials de Catalunya, Edifici Nexus, c/ Capitá, 2-4, desp.
