Detection of 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 Be II in the ultraviolet spectra of V5669 Sgr during its early decline phase ( and d). We identified three blue-shifted absorption sys…
The similarity of the interstellar comet 2I/Borisov to solar system comets from high resolution optical spectroscopy
C. Opitom, E. Jehin, D. Hutsemékers +11
2I/Borisov - hereafter 2I - is the first visibly active interstellar comet observed in the solar system, allowing us for the first time to sample the composition of a building bloc…
Absorption Lines in the 0.91-1.33 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…
Mid-infrared observations of the nucleus of comet P/2016 BA14 (PANSTARRS)
Takafumi Ootsubo, Hideyo Kawakita, Yoshiharu Shinnaka
We present mid-infrared observations of comet P/2016 BA14 (PANSTARRS), which were obtained on UT 2016 March 21.3 at heliocentric and geocentric distances of 1.012 au and 0.026 au,…
