We have explored radial color and stellar surface mass density profiles for a sample of 85 late-type galaxies with available deep (down to˜27.0mag/arcsec2) SDSS...

The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a near-infrared (1.5-1.7 microns), high resolution (R~22,500), high S/N (>100)...

The highly modulated optical light curve of HD 79826 (spectral types G5+M5) was discovered in the \chan guide-star light curves, indicating a period of about 0...

The highly modulated optical light curve of HD 79826 (spectral type G5) was discovered in the Chandra guide-star light curves, indicating a period of about 0.5...

Stars similar to the Sun, known as solar analogues, provide an excellent opportunity to study the preceding and following evolutionary phases of our host star...

Recent MHD 3D modelling of the Proxima system predicts that the interaction of the planet Proxima b with its host star, Proxima, would be proceeding in the...

The surface magnetic field has substantial influence on various stellar properties that can be probed through various techniques. With the advent of new space...

More than 4000 exoplanets are known to date in systems that differ greatly from our Solar System. In particular, inner exoplanets tend to follow orbits around...
