Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle
B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58
The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…
Third Nearest WZ Sge-Type Dwarf Nova candidate ASASSN-14dx Classified on the Basis of Gaia Data Release 2
Keisuke Isogai, Taichi Kato, Akira Imada +8
ASASSN-14dx showed an extraordinary outburst whose features are the small outburst amplitude (~ 2.3 mag) and long duration (> 4 years). Because we found a long observational gap of…
Shell Inhomogeneities of the Single-Particle Level Spectra in the Practical Model of the Gamma-Decay of Neutron Resonance
N. Jovančević, L. V. Mitsyna, A. M. Sukhovoj +7
In this paper we have taken into account shell inhomogeneities of the single-particle level spectra in the practical model of the gamma-decay of neutron resonance developed in Dubn…
Phase-dependent photometric and spectroscopic characterization of the MASTER-Net Optical Transient J212444.87+321738.3: an oxygen rich Mira
Supriyo Ghosh, Soumen Mondal, Ramkrishna Das +4
We describe the time-dependent properties of a new spectroscopically confirmed Mira variable, which was discovered in 2013 as MASTER-Net Optical Transient (OT) J212444.87+321738.3…
Detection of the Supercycle in V4140 Sagittarii: First Eclipsing ER Ursae Majoris-like Object
Taichi Kato, Franz-Josef Hambsch, Lewis M. Cook
We observed the deeply eclipsing SU UMa-type dwarf nova V4140 Sgr and established the very short supercycle of 69.7(3) d. There were several short outbursts between superoutbursts.…
ASASSN-16dt and ASASSN-16hg: Promising Candidates for a Period Bouncer
Mariko Kimura, Keisuke Isogai, Taichi Kato +13
We present optical photometry of superoutbursts in 2016 of two WZ Sge-type dwarf novae (DNe), ASASSN-16dt and ASASSN-16hg. Their light curves showed a dip in brightness between the…
