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…
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,…
Photometry and high-resolution spectroscopy of comet 21P/Giacobini-Zinner during its 2018 apparition
Y. Moulane, E. Jehin, P. Rousselot +7
We report on photometry and high resolution spectroscopy of the chemically peculiar Jupiter-family Comet (hereafter JFC) 21P/Giacobini-Zinner. Comet 21P is a well known member of t…
High-resolution optical spectroscopic observations of comet 21P/Giacobini-Zinner in Its 2018 apparition
Yoshiharu Shinnaka, Hideyo Kawakita, Akito Tajitsu
Comet 21P/Giacobini-Zinner is a peculiar comet from the viewpoints of the chemical and physical properties of its dust grains. We conduct optical high-resolution spectroscopic obse…
Amateur telescopes discover a kilometre-sized Kuiper belt object from stellar occultation
K. Arimatsu, K. Tsumura, F. Usui +7
Kuiper belt objects (KBOs) are thought to be the remnant of the early solar system, and their size distribution provides an opportunity to explore the formation and evolution of th…
