Deep CO Observations and the CO-to-H_2 Conversion Factor in DDO 154, a Low Metallicity Dwarf Irregular Galaxy

Shinya Komugi, Chikako Yasui, Naoto Kobayashi +4

We present a deep spectroscopic search for CO emission in the dwarf irregular galaxy DDO154, which has an Oxygen abundance of only 1/20 the solar value. The observations were condu…

Short Lifetime of Protoplanetary Disks in Low-metallicity Environments

Chikako Yasui, Naoto Kobayashi, Alan T. Tokunaga +2

We studied near-infrared disk fractions of six young clusters in the low-metallicity environments with [O/H using deep images with Subaru 8.2\,m telescope. We fo…
