Computational Investigations of the Primary Excited States of Poly(para-phenylene vinylene)

Robert J. Bursill, William Barford

The Pariser-Parr-Pople model of pi-conjugated electrons is solved by the density matrix renormalization group method for the light emitting polymer, poly(para-phenylene vinylene).…

A CH3CN and HCO+ survey towards southern methanol masers associated with star formation

C. R. Purcell, R. Balasubramanyam, M. G. Burton +32

We present the initial results of a 3-mm spectral line survey towards 83 methanol maser selected massive star-forming regions. Here we report observations of the J=5-4 and 6-5 rota…

Primordial pollution of globular clusters within their host dwarfs embedded in dark matter halos at high redshifts

Kenji Bekki

Recent observational studies have revealed star-to-star abundance inhomogeneity among light elements (e.g., C, N, O, Na, and Al) of stars on the main sequence in the Galactic globu…

The origin of the double main sequence in Omega Centauri: Helium enrichment due to gas fueling from its ancient host galaxy ?

Kenji Bekki, John E. Norris

Recent observational studies of Centauri by {\it Hubble Space Telescope} have discovered a double main sequence in the color magnitude diagrams (CMDs) of its stellar population…

L-band (3.5 micron) IR-excess in massive star formation, II. RCW 57/NGC 3576

M. Maercker, M. G. Burton, C. M. Wright

We present a JHKL survey of the massive star forming region RCW 57 (NGC 3576) based on L-band data at 3.5 micron taken with SPIREX (South Pole Infrared Explorer), and 2MASS JHK dat…
