Dust Around Herbig AE/Be Stars

Suh, Kyung-Won

We model dust around Herbig Ae/Be stars using a radiative transfer model for multiple isothermal circumstellar dust shells to reproduce the multiple broad peaks in their spectral energy distributions (SEDs). Using the opacity functions for various types of dust grains at different temperatures, we calculate the radiative transfer model SEDs for mu…

Hubble Space Telescope Imaging of Globular Clusters in Two Face-On Low Surface Brightness Galaxies UGC 5981 and UGC 6614

Kim, Ji Hoon

We present a study searching for globular cluster systems (GCSs) of two face-on low surface brightness galaxies (LSBGs), UGC 5981 and UGC 6614. Based on HST WFPC2 images of F555W and F814W filters, we detect 12 and 18 GC candidates for UGC 5981 and UGC 6614, respectively. Although these two LSBGs have very different bulge properties, they have ver…

The Properties of the Stellar Nuclei with the Host Galaxy Morphology in the ACSVCS

Lee, Hyun-Chul

We have revisited the ACS Virgo Cluster Survey (ACSVCS), a Hubble Space Telescope program to obtain ACS/WFC g and z bands imaging for a sample of 100 early-type galaxies in the Virgo Cluster. In this study, we examine 51 nucleated early-type galaxies in the ACSVCS in order to look into the relationship between the photometric and structural proper…

Effect of Fir Fluxes on Constraining Properties of YSOs

Lee, Jeong-Eun; Jeong, Woong-Seob; Ha, Ji-Sung Ha

Young Stellar Objects (YSOs) in the early evolutionary stages are very embedded, and thus they emit most of their energy at long wavelengths such as far-infrared (FIR) and submillimeter (Submm). Therefore, the FIR observational data are very important to classify the accurate evolutionary stages of these embedded YSOs, and to better constrain thei…
