A Very Metal-poor RR Lyrae Star with a Disk Orbit Found in the Solar Neighborhood
Noriyuki Matsunaga, Akinori Itane, Kohei Hattori +28
Metal-deficient stars are important tracers for understanding the early formation of the Galaxy. Recent large-scale surveys with both photometric and spectroscopic data have report…
Against the biases in spins and shapes of asteroids
A. Marciniak, F. Pilcher, D. Oszkiewicz +21
Physical studies of asteroids depend on an availability of lightcurve data. Targets that are easy to observe and analyse naturally have more data available, so their synodic period…
The astrometric Gaia-FUN-SSO observation campaign of 99 942 Apophis
W. Thuillot, D. Bancelin, A. Ivantsov +71
Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected by ESA's Gai…
Discovery of Mira variable stars in the metal-poor Sextans dwarf spheroidal galaxy
T. Sakamoto, N. Matsunaga, T. Hasegawa +1
We report the discovery of two Mira variable stars (Miras) toward the Sextans dwarf spheroidal (dSph) galaxy. We performed optical long-term monitoring observations for two red sta…
Kinematics of Red Variables in the Solar Neighborhood I. Basic Data Obtained by an SiO Maser Survey
S. Deguchi, T. Sakamoto, T. Hasegawa
In order to study the streaming motions of miras in the Solar neighborhood, we newly surveyed 379 red variables in the SiO maser lines at 42.821 and 43.122 GHz with the Nobeyama 45…
Photometric Observations of 107P/Wilson-Harrington
Seitaro Urakawa, Shin-ichiro Okumura, Kota Nishiyama +14
We present lightcurve observations and multiband photometry for 107P/Wilson-Harrington using five small- and medium-sized telescopes. The lightcurve has shown a periodicity of 0.29…
