The nova rebrightened several times. The spectra during the early phase showed emission lines of H α, H β, O I, He I, He II, N II, Fe II. Nova V5587 Sgr is classified into the Fe II type. The helium abundance of the nova is estimated as <em>N</em>(He)/<em>N</em>(H) = 0.134 ± 0.09. The light curve, the spectral evolution, and the helium abundance in V5587 Sgr are similar to those of the nova PW Vul.}, number={1}, journal={Acta Polytechnica CTU Proceedings}, author={Kajikawa, T. and Arai, A. and Nagashima, M. and Kawakita, H. and Yamanaka, M. and Kawabata, K. and Kiyota, S.}, year={2015}, month={Feb.}, pages={242–245} }
