White dwarfs sing the blues [PDF]
A new model predicts that the oldest white dwarf stars should look blue. That could help to identify what makes up the massive halo of our Galaxy, and to pin down the age of the Universe.

Cometary Blue Compact Dwarf Galaxies:
Astrophysics and Space Science, 2001‘Cometary’ Blue Compact Dwarf Galaxies (iI,C BCDs) are characterized by off-center starbursts close to the end of an elongated dwarf irregular (dI)-like host galaxy. This may either represent randomly enhanced star-forming activity of a dI, or may be caused by a set of special properties of such systems or their environment.

Isolated groups of extremely blue dwarf galaxies [PDF]
AbstractInteractions and mergers between dwarf galaxies are mostly gas-rich and should be marked by an intense star formation activity. But these processes, which are expected to be common at earlier times, are very difficult to observe at low redshifts. To investigate that, we look in the Sloan Digital Sky Survey (SDSS) for compact groups that contain

The hosts of blue compact dwarf galaxies in MaNGA
Proceedings of the International Astronomical Union, 2018AbstractBlue compact dwarf galaxies(BCDs) are galaxies undergoing violent burst of star formation in compact regions. They are often thought of being an evolutionary stage of dwarf galaxies and thus can provide a unique window to study the formation and evolution of dwarf galaxies.

On the Metallicity of Blue Compact Dwarfs
2011Based on the even distribution of metals in Blue Compact Dwarfs (BCDs) spread all over their volume, we show that a large amount of stars (≥108 M⊙) are required to justify such a homogeneous metal abundance. We also show that such a mass would imply a large number of bursts similar to the ones presently energizing the giant nebulae.

Blue Compact Dwarfs: Extreme Dwarf Irregular Galaxies
1987In Hubble’s classification scheme, dwarf irregular galaxies (dIs) are low luminosity systems (MB≳ -16) which are at the end of the galaxy morphological sequence and which lack both a dominating nucleus and rotational symmetry [1]. We concentrate here on a class of dIs which are so extreme in these properties that they appear almost stellar in ...

Globular Clusters, White Dwarfs, and Blue Stragglers
1998One of the fundamental concepts in astronomy is that the stars of a given cluster formed at about the same time. This can be seen easily in a Hertzsprung-Russell diagram, where the colors of the stars are plotted against their brightnesses. The diagram is not evenly populated but shows several preferred areas; the main sequence, corresponding to the ...
