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…
Discovery of Star Formation in the Extreme Outer Galaxy Possibly Induced by a High-velocity Cloud Impact
Natsuko Izumi, Naoto Kobayashi, Chikako Yasui +3
We report the discovery of star formation activity in perhaps the most distant molecular cloud in the extreme outer galaxy. We performed deep near infrared imaging with the Subaru…
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…
Formation of a Keplerian disk in the infalling envelope around L1527 IRS: transformation from infalling motions to Kepler motions
Nagayoshi Ohashi, Kazuya Saigo, Yusuke Aso +9
We report Atacama Large Millimeter/submillimeter Array (ALMA) cycle 0 observations of CO (), SO () and 1.3mm dust continuum toward L1527 IRS, a class 0…
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 Infalling Flows toward the Keplerian Disk around the Class I Protostar L1489 IRS
Hsi-Wei Yen, Shigehisa Takakuwa, Nagayoshi Ohashi +8
We have conducted ALMA observations in the 1.3 mm continuum and 12CO (2-1), C18O (2-1) and SO (5_6-4_5) lines toward L1489 IRS, a Class I protostar surrounded by a Keplerian disk a…
