Detection of Remnant Dust Cloud Associated with the 2007 Outburst of 17P/Holmes
Masateru Ishiguro, Yuki Sarugaku, Daisuke Kuroda +11
This paper reports a new optical observation of 17P/Holmes one orbital period after the historical outburst event in 2007. We detected not only a common dust tail near the nucleus,…
High dispersion spectroscopy of solar-type superflare stars with Subaru/HDS
Yuta Notsu, Satoshi Honda, Hiroyuki Maehara +4
We carried out spectroscopic observations with Subaru/HDS of 50 solar-type superflare stars found from Kepler data. More than half (34 stars) of the target stars show no evidence o…
The 2010 Eruption of the Recurrent Nova U Scorpii: The Multi-Wavelength Light Curve
Ashley Pagnotta, Bradley E. Schaefer, James L. Clem +8
The recurrent nova U Scorpii most recently erupted in 2010. Our collaboration observed the eruption in bands ranging from the Swift XRT and UVOT w2 (193 nm) to K-band (2200 nm), wi…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. VII: The Seventh Year (2014-2015)
Taichi Kato, Franz-Josef Hambsch, Pavol A. Dubovsky +89
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly during the 2014-2015…
High Dispersion Spectroscopy of Solar-type Superflare Stars. III. Lithium Abundances
Satoshi Honda, Yuta Notsu, Hiroyuki Maehara +4
We report on the abundance analysis of Li in solar-type (G-type main sequence) superflare stars which were found by the analysis of Kepler photometric data. Li is a key element to…
Statistical properties of superflares on solar-type stars based on 1-min cadence data
Hiroyuki Maehara, Takuya Shibayama, Yuta Notsu +4
We searched for superflares on solar-type stars using Kepler data with 1 min sampling in order to detect superflares with short duration. We found 187 superflares on 23 solar-type…
