Rotational properties of Maria asteroid family

Myung-Jin Kim, Young-Jun Choi, Hong-Kyu Moon +13

Maria family is regarded as an old-type (~3 +/- 1 Gyr) asteroid family which has experienced substantial collisional and dynamical evolution in the Main-belt. It is located nearby…

Estimating the parameters of globular cluster M 30 (NGC 7099) from time-series photometry

N. Kains, D. M. Bramich, A. Arellano Ferro +47

We present the analysis of 26 nights of V and I time-series observations from 2011 and 2012 of the globular cluster M 30 (NGC 7099). We used our data to search for variable stars i…

Microlensing Discovery of a Population of Very Tight, Very Low-mass Binary Brown Dwarfs

J. -Y. Choi, C. Han, A. Udalski +121

Although many models have been proposed, the physical mechanisms responsible for the formation of low-mass brown dwarfs are poorly understood. The multiplicity properties and minim…
