The Constellation-X mission is a high through-put X-ray facility, emphasizing observations at high spectral resolution (Delta E/E 300 to 3000) while covering a...

During the early stages of planetary formation, planets undergo strong changes in their physical and orbital properties due to internal and external forces...

An ongoing study is presented in which a photometric non-linear Scaling Relation of Early-Type Galaxies (ETGs) is proposed to carry out a consistency test on...

Understanding the complexities of galaxy evolution and the role of mergers therein remains a fundamental challenge in astrophysics. Since galaxies can only be...

The evolution of stars and their hosting binary systems is a highly interactive process and cannot be investigated in a segregated manner. Due to the...

The evolution of the core rotation rate of red giant stars is a key parameter in understanding the stellar behavior in the late phases of stellar evolution...

The dynamics of a barred galaxy depends on the pattern speed of its bar. The only direct method for measuring the pattern speed of a bar is the Tremaine...

We propose to have simultaneously X-ray and optical observations of the two X-ray binaries 4U 1254-69 4U 1916-053 using the rare combination of RXTE and...
