Formation of unipolar outflow and in magnetized turbulent molecular cloud cores
Daisuke Takaishi, Yusuke Tsukamoto, Miyu Kido +4
Observed protostellar outflows exhibit a variety of asymmetrical features, including remarkable unipolar outflows and bending outflows. Revealing the formation and early evolution…
Constraining the binarity of black hole candidates: a proof-of-concept study of Gaia BH1 and Gaia BH2
Toshinori Hayashi, Yasushi Suto, Alessandro A. Trani
Nearly a hundred of binary black holes (BBHs) have been discovered with gravitational-wave signals emitted at their merging events. Thus, it is quite natural to expect that signifi…
Modeling photometric variations due to a global inhomogeneity on an obliquely rotating star: application to lightcurves of white dwarfs
Yasushi Suto, Shin Sasaki, Masataka Aizawa +2
We develop a general framework to compute photometric variations induced by the oblique rotation of a star with an axisymmetric inhomogeneous surface. We apply the framework to com…
Lagrange vs. Lyapunov stability of hierarchical triple systems: dependence on the mutual inclination between inner and outer orbits
Toshinori Hayashi, Alessandro A. Trani, Yasushi Suto
While there have been many studies examining the stability of hierarchical triple systems, the meaning of ``stability'' is somewhat vague and has been interpreted differently in pr…
Dynamical disruption timescales and chaotic behavior of hierarchical triple systems
Toshinori Hayashi, Alessandro A. Trani, Yasushi Suto
We examine the stability of hierarchical triple systems using direct -body simulations without adopting a secular perturbation approximation. We estimate their disruption timesc…
Meta-analysis of photometric and asteroseismic measurements of stellar rotation periods: the Lomb-Scargle periodogram, autocorrelation function, wavelet and rotational splitting analysis for 92 Kepler asteroseismic targets
Yuting Lu, Othman Benomar, Shoya Kamiaka +1
We perform photometric (the Lomb-Scargle periodogram, autocorrelation, and wavelet) and asteroseismic analyses of 92 Kepler solar-like main-sequence stars to understand the reliabi…
