Effect of Magnetic Field on the Accretion Phase of Population III Star Formation
Masahiro N. Machida, Shingo Hirano, Shantanu Basu
We examine the impact of the magnetic field on Population III star formation by varying the magnetic field strength. We perform simulations with magnetic field strengths ranging fr…
Dark Matter Density Profile Around a Newborn First Star
Shingo Hirano, Naoki Yoshida
Ambient dark matter (DM) around binary black holes can imprint characteristic signatures on gravitational waves emitted from their merger. The exact signature depends sensitively o…
Velocity Structure of Circumstellar Environment around Class 0/I Protostars: Uncertainty in the Protostellar Mass Estimation Using Circumstellar Velocities
Shingo Hirano, Yuri Aikawa, Masahiro N. Machida
Recent high-resolution observations have enabled detailed investigations of the circumstellar environments around Class 0/I protostars. Several studies have reported that the infal…
