Does Magnetic Levitation or Suspension Define the Masses of Forming Stars?

Frank H. Shu, Zhi-Yun Li, Anthony Allen

We investigate whether magnetic tension can define the masses of forming stars by holding up the subcritical envelope of a molecular cloud that suffers gravitational collapse of it…

Collapse of Magnetized Singular Isothermal Toroids: II. Rotation and Magnetic Braking

A. Allen, Z. Y. Li, F. H. Shu

We study numerically the collapse of rotating, magnetized molecular cloud cores, focusing on rotation and magnetic braking during the main accretion phase of isolated star formatio…

Collapse of Magnetized Singular Isothermal Toroids: I. Non-Rotating Case

A. Allen, F. H. Shu, Z. Y. Li

We study numerically the collapse of non-rotating, self-gravitating, magnetized, singular isothermal toroids characterized by sound speed, , and level of magnetic to thermal sup…

Radio Cores of Bipolar Nebulae: Search for Collimated Winds

Ting-Hui Lee, Jeremy Lim, Sun Kwok

We present results of our search for collimated ionized winds in bipolar nebulae using the Very Large Array (VLA) and the Australia Telescope Compact Array (ATCA). Our search is mo…

Numerical Examination of the Stability of an Exact Two-dimensional Solution for Flux Pile-up Magnetic Reconnection

S. Hirose, Y. Litvinenko, S. Tanuma +9

The Kelvin--Helmholtz (KH) and tearing instabilities are likely to be important for the process of fast magnetic reconnection that is believed to explain the observed explosive ene…

A Search for Interstellar Pyrimidine

Yi-Jehng Kuan, Chi-Hung Yan, Steven B. Charnley +3

We have searched three hot molecular cores for submillimeter emission from the nucleic acid building-block pyrimidine. We obtain upper limits to the total pyrimidine (beam-averaged…

High-energy Emission from Pulsar Outer Magnetospheres

Kouichi Hirotani

We investigate a stationary pair production cascade in the outer magnetosphere of an isolated, spinning neutron star. The charge depletion due to global flows of charged particles,…

Molecular Evolution in Collapsing Prestellar Cores II: The Effect of Grain-surface Reactions

Yuri Aikawa, Nagayoshi Ohashi, Eric Herbst

The molecular evolution that occurs in collapsing prestellar cores is investigated. To model the dynamics, we adopt the Larson-Penston (L-P) solution and analogues with slower rate…

Star Formation and the ISM in Four Dwarf Irregular Galaxies

L. M. Young, L. van Zee, K. Y. Lo +2

We present new, high sensitivity VLA observations of HI in four dwarf galaxies (UGCA 292, GR8, DDO 210, and DDO 216) and we use these data to study interactions between star format…

E/B Separation in CMB Interferometry

Chan-Gyung Park, Kin-Wang Ng

We study the problem of separating E and B modes in interferometric observations of the polarization of the cosmic microwave background. The E and B band powers and their mixings a…

Interaction between the Outflow and the Core in IRAM 04191+1522

Shigehisa Takakuwa, Nagayoshi Ohashi, Naomi Hirano

We have carried out mapping observations of the molecular core associated with the young Class 0 protostar, IRAM 04191+1522, in the CH3OH (JK=2K-1K) and C34S (J=2-1) lines using th…

The Effect of Tidal Inflation Instability on the Mass and Dynamical Evolution of Extrasolar Planets with Ultra-Short Periods

Pin-Gao Gu, Doug Lin, Peter Bodenheimer

We investigate the possibility of substantial inflation of short-period Jupiter-mass planets, as a result of their internal tidal dissipation associated with the synchronization an…

Variability of Sagittarius A* - Flares at 1 Millimeter

Jun-Hui Zhao, K. H. Young, R. M. Herrnstein +5

We report the results from recent observations of Sgr A* at short-/sub-millimeter wavelengths made with the partially finished Sub-Millimeter Array (SMA) on Mauna Kea. A total of 2…
