The quest for clusters - census of the obscured cluster
population in the Milky Way
|
| Abstract |
The Milky Way cluster census is important for both estimating
the current star formation rate in the Milky way and for constraining
the merging history of the Galaxy. We searched for obscured clusters
based on various infrared sky surveys that can circumvent the
extinction problem. Cluster candidates were selected from a combination
of stellar surface density maps and visual inspection, and their
properties were determined from deep near-infrared photometry and
spectroscopy. The majority of the new clusters have intermediate masses
(1000-5000 Msun) and ages of a few million years. They are all located
within the nearest 4-7 kpc. Some of them have Wolf-Rayer members. We
have alsoidentified two new globulars.

Observational Models for
Extrasolar Planets |
| Abstract |
Within the 10 years, next generation telescopes such as TPF
and will be capable of directly observation Extrasolar planets and
collecting spectrography data from them. The theoretical framework for
interpreting that data needs a strong foundation based on comparisons
to the solar system planets. In this presentation I discuss preliminary
observations performed at Hiroshima Observatory and plans for future
Antarctic observations, which together will create a planet observation
library for comparison with Extrasolar planet simulations and
observations. |
