| Abstract: |
| To discover and study the morphological structures of PNe using high-angular resolution optical and near-infrared imaging observations, and to understand the dynamical origin of these sturctures; to map the chemical distribution of ionized gases, molecules, and solid particles in PNe in order to understand the formation history and inter-relationships between these components; to derive the kinematic structures of PNe by mapping the distribution of molecular emissions using high angular resolution imaging spectroscopy with the Submillimeter Array. |

| Start Date: | 07/2008 |
| Abstract: |
| 1) perform spectroscopic studies Asymptotic Giant Branch stars, proto-planetary nebulae, and planetary nebulae to search for new vibrational features and measure the relative strengths of the features as a function of stellar evolution; 2) perform imaging spectroscopy to determine the spatial distribution of the emitting substances in the envelopes; 3) compare with laboratory spectroscopic studies with the goal of identifying the chemical composition of unidentified emission featurres |

| Project Title: | Study of Infrared Nebulae found in the Spitzer Space Telescope Galactic Plane Survey |
| Investigator(s): | Kwok S |
| Department: | Science Faculty |
| Source(s) of Funding: | General Research Fund (GRF) |
| Start Date: | 07/2009 |
| Abstract: |
| 1) Through processing of data obtained in the GLIMPSE survey, we plan to discover and identify new infrared extended emission sources and classify them by their astronomical nature. 2) From follow-up ground-based observations in radio continuum, molecular line spectroscopy, and near-infrared imaging, we plan to study the radiative and chemical interactions between the atomic, molecular and solid-state components. 3) From the photometric colors of the nebulae, we plan to study the extent of aromatic compounds' contribution to the infrared emission of the nebulae and the abundance of organic matter in the diffuse interstellar medium. |
