Active-Region Tilt Angles: Magnetic Versus White-Light Determinations of Joy's Law
Y. -M. Wang, R. C. Colaninno, T. Baranyi +1
The axes of solar active regions are inclined relative to the east--west direction, with the tilt angle tending to increase with latitude ("Joy's law"). Observational determination…
Star formation in turbulent molecular clouds with colliding flow
Tomoaki Matsumoto, Kazuhito Dobashi, Tomomi Shimoikura
Using self-gravitational hydrodynamical numerical simulations, we investigated the evolution of high-density turbulent molecular clouds swept by a colliding flow. The interaction o…
A Spitzer Five-Band Analysis of the Jupiter-Sized Planet TrES-1
Patricio Cubillos, Joseph Harrington, Nikku Madhusudhan +4
With an equilibrium temperature of 1200 K, TrES-1 is one of the coolest hot Jupiters observed by {\Spitzer}. It was also the first planet discovered by any transit survey and one o…
Colliding Filaments and a Massive Dense Core in the Cygnus OB 7 Molecular Cloud
Kazuhito Dobashi, Tomoaki Matsumoto, Tomomi Shimoikura +4
We report results of molecular line observations carried out toward a massive dense core in the Cyg OB 7 molecular cloud. The core has an extraordinarily large mass ($\sim1.1 \time…
Angular Momentum Exchange by Gravitational Torques and Infall in the Circumbinary Disk of the Protostellar System L1551 NE
Shigehisa Takakuwa, Masao Saito, Kazuya Saigo +4
We report the ALMA observation of the Class I binary protostellar system L1551 NE in the 0.9-mm continuum, C18O (3-2), and 13CO (3-2) lines at a ~1.6 times higher resolution and a…
ALMA observations of a high-density core in Taurus: dynamical gas interaction at the possible site of a multiple star formation
Kazuki Tokuda, Toshikazu Onishi, Kazuya Saigo +7
Starless dense cores eventually collapse dynamically, which forms protostars inside them, and the physical properties of the cores determine the nature of the forming protostars. W…
