The ALMaQUEST Survey: The Molecular Gas Main Sequence and the Origin of the Star-forming Main Sequence [PDF]
The Astrophysical Journal Letters, 2019 The origin of the star-forming main sequence (SFMS; i.e., the relation between star formation rate and stellar mass, globally or on kpc scales) remains a hotly debated topic in galaxy evolution.

Blue Stragglers After the Main Sequence [PDF]
The Astrophysical Journal, 2008 We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases.

Entropy Production of Main-Sequence Stars [PDF]
Entropy, 2015 The entropy production (inside the volume bounded by a photosphere) of main-sequence stars is calculated based on B–V photometry data. The entropy-production distribution function and the dependences of entropy production on temperature and luminosity ...

The Pre--Main-Sequence of A-type stars [PDF]
Proceedings of the International Astronomical Union, 2004 Young A-type stars in the pre--main-sequence (PMS) evolutionary phase are particularly interesting objects since they cover the mass range (1.5-4 solar ma sses) which is most sensitive to the internal conditions inherited during the protostellar phase ...

On the Statistical Properties of the Lower Main Sequence [PDF]
The Astrophysical Journal, 2017 Astronomy is in an era where all-sky surveys are mapping the Galaxy. The plethora of photometric, spectroscopic, asteroseismic, and astrometric data allows us to characterize the comprising stars in detail. Here we quantify to what extent precise stellar

The Ages of Pre-main-sequence Stars [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 The position of pre-main-sequence or protostars in the Hertzsprung--Russell diagram is often used to determine their mass and age by comparison with pre-main-sequence evolution tracks.

Abundances on the Main Sequence of Omega Centauri [PDF]
The Astrophysical Journal, 2007 Abundance ratios of carbon, nitrogen and strontium relative to iron, calculated using spectrum synthesis techniques, are given for a sample of main sequence and turnoff stars that belong to the globular cluster omega Centauri.

Asteroseismology of stars on the upper main sequence [PDF]
Proceedings of Frank N. Bash Symposium 2011: New Horizons in Astronomy — PoS(Bash11), 2012 I review the properties of pulsators located on the upper main sequence in the HR diagram and discuss asteroseismic inferences on the internal structure of stars of spectral type A and B.
