The Astrophysical Journal, 2023 We present the results of our Hubble Space Telescope far-ultraviolet survey of the blue lurkers (BLs) in M67. We find evidence for two white dwarf (WD) companions among the BLs that are indicative of mass transfer from an evolved companion, one in WOCS ...

BLUE STRAGGLERS AFTER THE MAIN SEQUENCE [PDF]
The Astrophysical Journal, 2009 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. We found that the blue straggler progeny populate the colour-magnitude diagram slightly blueward of the red giant branch and between 0.2 and 1 ...

Primordial binary evolution and blue stragglers [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractBlue stragglers have been found in all populations. They are important in both stellar evolution and stellar population synthesis. Much evidence shows that blue stragglers are relevant to primordial binaries. Here, we summarize the links between binary evolution and blue stragglers, describe the characteristics of blue stragglers originating ...

Building Blue Stragglers with Stellar Collisions [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product with an (evolved) main sequence star, or assume that the collision product was completely mixed during the collision.It is known from hydrodynamical simulations of ...

SPINNING LIKE A BLUE STRAGGLER: THE POPULATION OF FAST ROTATING BLUE STRAGGLER STARS IN ω CENTAURI [PDF]
The Astrophysical Journal, 2014 By using high-resolution spectra acquired with FLAMES-GIRAFFE at the ESO/VLT, we measured radial and rotational velocities for 110 Blue Straggler stars (BSSs) in Omega Centauri, the globular cluster-like stellar system harboring the largest known BSS population. According to their radial velocities, 109 BSSs are members of the system.

SPECTRAL INVESTIGATION OF FIELD BLUE STRAGGLERS
Odessa Astronomical Publications, 2017 Field blue stragglers are counterparts of cluster blue stragglers. They were selected by Olsen in base of specific Stromgren indices among bright metal-deficient early F dwarfs. For some stars from this list, the high-resolution and high S/N CCD spectra

Chemical abundances and evolutionary status of some lambda Bootis type stars and FBSwl
Odessa Astronomical Publications, 2017 Comparative analysis of chemical abundances in the atmospheres of lambda Bootis type stars and FBSwl (field blue stragglers week lined) is presented. Evolutionary status of these metal deficient stars is discussed.

The lithium abundance of M67 blue stragglers - A constraint on the blue straggler phenomenon
The Astrophysical Journal, 1991 Upper limits have been placed on the line strength of the 6707 A Li I resonance doublet in seven blue stragglers in M67. The corresponding upper limits on abundances range from log N(Li) less than about 1.3 to less than about 2.3. This result is significantly below the level of log N(Li) about 3.1 + or {minus} 0.1 found in field main-sequence stars of ...
