The Molecular Envelope around the Red Supergiant VY CMa
We present millimeter interferometric observations of the molecular envelope around the red supergiant VY CMa with the Submillimeter Array (SMA). The high angular resolution (<2'') allows us toExpand
The Circumnuclear Molecular Gas in the Seyfert Galaxy NGC 4945
We have mapped the central region of NGC 4945 in the J = 2 → 1 transition of 12CO, 13CO, and C18O, as well as the continuum at ~1.3 mm, at an angular resolution of 5'' × 3'' with the SubmillimeterExpand
An eclipsing millisecond pulsar in the globular cluster Terzan 5
WE HAVE discovered an eclipsing binary millisecond pulsar in the globular cluster Terzan 5. This, the second known eclipsing binary pulsar after PSR1957 + 20, has a pulse period of 11.56 ms and aExpand
The magnetic field topology plays an important role in the understanding of stellar magnetic activity. While it is widely accepted that the dynamo action present in low-mass partially convectiveExpand
Structure and Kinematics of CO?J?=?2-1 Emission in the Central Region of NGC?4258
We present 12CO J = 2-1 observations toward the central region of the type 2 Seyfert galaxy NGC 4258 with the Submillimeter Array (SMA). Our interferometric maps show two armlike elongated componentsExpand
Mapping the Outflow from G5.89–0.39 in SiO J = 5 → 4
We have mapped the ultracompact H II region, G5.89-0.39, and its molecular surroundings with the Submillimeter Array at 28 × 18 angular resolution in 1.3 mm continuum, SiO J = 5 → 4, and eight otherExpand
Molecular Gas in the Powerful Radio Galaxies 3C 31 and 3C 264: Major or Minor Mergers?
We report the detection of 12CO (1 → 0) and 12CO (2 → 1) emission from the central regions (5-10 kpc) of the two powerful radio galaxies 3C 31 and 3C 264. Their individual CO emission exhibits aExpand
Submillimeter Array Outflow/Disk Studies in the Massive Star-forming Region IRAS 18089?1732
Submillimeter Array observations of the massive star-forming region IRAS 18089-1732 in the 1 mm and 850 ?m band reveal outflow and disk signatures in different molecular lines. The SiO (5-4) dataExpand
Discovery of Radio Emission from the Tight M8 Binary LP 349–25
We present radio observations of eight ultracool dwarfs with a narrow spectral type range (M8-M9.5) using the Very Large Array at 8.5 GHz. Only the tight M8 binary LP 349-25 was detected. LP 349-25Expand
Discovery of ten millisecond pulsars in the globular cluster 47 Tucanae
IN the past four years a total of 13 millisecond pulsars have been found in 12 different globular clusters. These pulsars are believed to be old neutron stars that have been spun up ('recycled') inExpand
