Blue straggler stars in dwarf spheroidal galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 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 stars has been a point of debate.

Red giants in blue dwarfs [PDF]
Nature, 1998 Most galaxies that we observe are ancient, containing some stars almost as old as the Universe. But blue compact dwarf galaxies (BCDs) had been thought younger — rare baby galaxies in among the adults. Now that is called into doubt by observations of a nearby BCD, observations sharp enough to resolve old red giant stars. It may be that there are no new

The Blue Compact Dwarf Galaxy VCC 848 Formed by Dwarf-Dwarf Merging: HI Gas, Star Formation and Numerical Simulations [PDF]
The Astrophysical Journal, 2020 Abstract A clear link between a dwarf–dwarf merger event and enhanced star formation (SF) in the recent past was recently identified in the gas-dominated merger remnant VCC 848, offering by far the clearest view of a gas-rich late-stage dwarf–dwarf merger.

Coat protein expression strategy of oat blue dwarf virus. [PDF]
Virology, 2014 Oat blue dwarf virus (OBDV) is a member of the genus Marafivirus whose genome encodes a 227 kDa polyprotein (p227) ostensibly processed post-translationally into its functional components. Encoded near the 3' terminus and coterminal with the p227 ORF are ORFs specifying major and minor capsid proteins (CP).

The Blue Compact Dwarf Galaxy VCC 848 Formed by Dwarf–Dwarf Merging [PDF]
The Astrophysical Journal Letters, 2020 Abstract It has long been speculated that many starburst or compact dwarf galaxies are resulted from dwarf–dwarf galaxy merging, but unequivocal evidence for this possibility has rarely been reported in the literature. We present the first study of deep optical broadband images of a gas-dominated blue compact dwarf galaxy (BCD) VCC 848 ...

Uncovering blue diffuse dwarf galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Extremely metal poor (XMP) galaxies are known to be very rare, despite the large numbers of low-mass galaxies predicted by the local galaxy luminosity function. This paper presents a sub-sample of galaxies that were selected via a morphology-based search on SDSS images with the aim of finding these elusive XMP galaxies. By using the recently discovered
