    Blue straggler stars in dwarf spheroidal galaxies
    Blue straggler star (BSS) candidates have been observed in all old dwarf spheroidal galaxies (dSphs), however whether or not they are authentic BSSs or young...

    Blue straggler stars in dwarf spheroidal galaxies - II. Sculptor and Fornax
    The existence of blue straggler stars (BSSs) in dwarf spheroidal galaxies (dSphs) is still an open question. In fact, many BSS candidates have been observed in...

    Blue stragglers and the binary hypothesis
    An observational test of the binary hypothesis for the origin of blue straggler stars is conducted by searching for radial velocity variables among 30 blue...

    Blue supergiants as a progenitor of intermediate-luminosity red transients
    The current perspective about the explosions of massive hydrogen-rich blue supergiants is that they resemble SN 1987A. These so-called peculiar Type II...
