    • Abstract

       

      π Aquilae is a visual double star whose angular separation of 1 ”.4 is so small that the system has been regarded as a composite-spectrum binary. However, by taking advantage of the excellence of the site and optics of the Mount Wilson 100-inch telescope, we have been able to obtain spectra of each component separately; the spectral types are about G8 III and A2V

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
