Spectroscopic analysis of four post-AGB candidates
Pereira, C. B.; Arellano Ferro, A.; Muneer, S. +2 more
We have done a detailed abundance analysis of four unexplored candidate post- Asymptotic Giant Branch(AGB) stars IRAS 13110 - 6629, IRAS 17579 - 3121, IRAS 18321 - 1401 and IRAS 18489 - 0629 using high resolution spectra. We have constructed Spectral Energy Distributions (SED) for these objects using the existing photometric data combined with inf…
Radio Continuum Sources associated with the HH 92 and HH 34 Jets
Rodríguez, Luis F.; Reipurth, Bo; Chiang, Hsin-Fang
We present high angular resolution, high sensitivity 8.46 GHz (3.6 cm) radio continuum observations made toward the core of the HH 92 outflow with the Very Large Array in 2002-2003 and with the Expanded Very Large Array in 2011. We detect a group of three compact sources distributed in a region 2'' in extension and discuss their nature. We conclud…
