The Sunrise balloon-borne solar observatory is equipped with a one-meter aperture optical telescope, offering a unique platform for uninterrupted seeing-free observations across ul…
Diffraction modelling of a 2023 March 5 stellar occultation by subkilometer-sized asteroid (98943) 2001 CC21
Ko Arimatsu, Fumi Yoshida, Tsutomu Hayamizu +31
We present an analysis of a stellar occultation event caused by a near-Earth asteroid (98943) 2001 CC21, an upcoming flyby target in the Hayabusa2 extended mission, on March 5, 202…
Spectroscopic Observations of V455 Andromedae Superoutburst in 2007: the Most Exotic Spectral Features in Dwarf Nova Outbursts
Yusuke Tampo, Daisaku Nogami, Taichi Kato +10
We present our spectroscopic observations of V455 Andromedae during the 2007 superoutburst. Our observations cover this superoutburst from around the optical peak of the outburst t…
Spectrum variability of the active solar-type star Xi Bootis A
Yoichi Takeda, Satoshi Honda, Hikaru Taguchi +1
An extensive spectroscopic study on ξBoo A (chromospherically active solar-type star) was conducted based on the spectra obtained in 2008 December though 2010 May, with an aim to d…
Spectroscopic Determination of Capella's Photospheric Abundances: Possible Influence of Stellar Activity
Yoichi Takeda, Osamu Hashimoto, Satoshi Honda
Capella is a spectroscopic binary consisting of two G-type giants, where the primary (G8III) is a normal red-clump giant while the secondary (G0III) is a chromospherically-active f…
