Light Curve Analyses of the Eclipsing Binaries in the Small Magellan Cloud [PDF]
Journal of Astronomy and Space Sciences, 2008 Large survey observations such as the EROS, the MACHO and the OGLE projects have discovered a large number of eclipsing binaries in the extra galaxies and published their light curves.

Microlensing of Extended Stellar Sources [PDF]
, 1998 We investigate the feasibility of reconstructing the radial intensity profile of extended stellar sources by inverting their microlensed light curves. Using a simple, linear, limb darkening law as an illustration, we show that the intensity profile can ...

Extended stellar systems in the solar neighborhood [PDF]
Astronomy & Astrophysics, 2020 Context. Nearby stellar streams carry unique information on the dynamical evolution and disruption of stellar systems in the Galaxy, the mass distribution in the disk, and they provide unique targets for planet formation and evolution studies.

New infrared star clusters in the Northern and Equatorial Milky Way with 2MASS [PDF]
, 2003 We carried out a survey of infrared star clusters and stellar groups on the 2MASS J, H and K_s all-sky release Atlas in the Northern and Equatorial Milky Way (350 < l < 360, 0 < l < 230). The search in this zone complements that in the Southern Milky Way

Current Star Formation in the Outer Rings among Early-Type Disk Galaxies
, 2015 By using the ARRAKIS, the atlas of stellar rings in galaxies (Comeron et al. 2014) based on data of the S4G survey, we have compiled a list of early-type, S0-Sb, disk galaxies with outer stellar ring-like features (`pure' rings, R, or pseudorings, R ...

Stellar abundances of beryllium and CUBES [PDF]
, 2014 Stellar abundances of beryllium are useful in different areas of astrophysics, including studies of the Galactic chemical evolution, of stellar evolution, and of the formation of globular clusters.

Continuous stellar mass-loss in N-body models of galaxies [PDF]
, 2001 We present an N-body computer code - aimed at studies of galactic dynamics - with a CPU-efficient algorithm for a continuous (i.e. time-dependent) stellar mass-loss. First, we summarize available data on stellar mass-loss and derive the long-term (20 Gyr)

Coronal activity with XMM-Newton and Chandra
, 2008 XMM-Newton and Chandra have greatly deepened our knowledge of stellar coronae giving access to a variety of new diagnostics such that nowadays a review of stellar X-ray astronomy necessarily must focus on a few selected topics.

Finding non-eclipsing binaries through pulsational phase modulation
EPJ Web of Conferences, 2015 We present a method for finding binaries among pulsating stars that were observed by the Kepler Mission. We use entire four-year light curves to accurately measure the frequencies of the strongest pulsation modes, then track the pulsation phases at those

Unveiling the Structure and Dynamics of Red Giants With Asteroseismology
Frontiers in Astronomy and Space Sciences, 2020 The Kepler mission observed many thousands of red giants. The long time series, some as long as the mission itself, have allowed us to study red giants with unprecedented detail. Given that red giants are intrinsically luminous, and hence can be observed
