Detection of $^{7}$ Be II in the Classical Nova V5669 Sgr (Nova Sagittarii 2015 No.3)

Akira Arai, Akito Tajitsu, Hideyo Kawakita +1

We report the new detection of $^{7}$ Be II in the ultraviolet spectra of V5669 Sgr during its early decline phase ( $+ 24$ and $+ 28$ d). We identified three blue-shifted absorption sys…

Absorption Lines in the 0.91-1.33 $μ$ m Spectra of Red Giants for Measuring Abundances of Mg, Si, Ca, Ti, Cr, and Ni

K. Fukue, N. Matsunaga, S. Kondo +13

Red giants show a large number of absorption lines in both optical and near-infrared wavelengths. Still, the characteristics of the lines in different wave passbands are not necess…
