PENA, J. H. et al. HD 115520, a New δ Scuti Star. Rev. mex. astron. astrofis [online]. 2007, vol.43, n.1, pp. 217-224. ISSN 0185-1101.
While performing uvby- β photoelectric photometry of some RR Lyrae stars in Bootes, acquired in 2005 at the Observatorio Astronómico Nacional, México, we also observed several standard stars, HD115520 among them. After the reduction this star showed indications of variability and a compilation of all the data of this star reinforced this conclusion. In view of this, a new observing run was carried out in 2006 during which we were able to demonstrate its variability. We present here the data we acquired as well as some conclusions on its nature as a δ Scuti star.
