Formation Channels for Blue Straggler Stars [PDF]
In this chapter we consider two formation channels for blue straggler stars: 1) the merger of two single stars via a collision, and 2) those produced via mass transfer within a binary. We review how computer simulations show that stellar collisions are likely to lead to relatively little mass loss and are thus effective in producing a young population ...

An unexpected detection of bifurcated blue straggler sequences in the young globular cluster NGC 2173 [PDF]
Bifurcated patterns of blue straggler stars in their color--magnitude diagrams have atracted significant attention. This type of special (but rare) pattern of two distinct blue straggler sequences is commonly interpreted as evidence of cluster core-collapse-driven stellar collisions as an efficient formation mechanism.

The new detection of blue straggler stars in 50 open clusters using Gaia DR3 [PDF]
The particularly abundant presence of blue straggler stars (BSS) in Galactic open clusters offers favorable conditions for detailed studies on the statistical properties and the origin of the blue straggler population.

UOCS-XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat [PDF]
We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine learning-based algorithm, ML-MOC, on Gaia DR3 data, we find 546 sources as cluster members.

Field blue straggler stars: Discovery of white dwarf companions to blue metal-poor stars using UVIT/AstroSat [PDF]
Blue metal-poor (BMP) stars are the main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters.

Could the number of blue straggler stars help to determine the age of their parent globular cluster? [PDF]
A recent study shows, from an empirical deduction, that the number and the presence of the blue straggler stars (BSS) in an open cluster follow a function whose components are the ratio between age and the relaxation time, $\it f$, and a factor, $\varpi$

Photometric variability of blue straggler stars in M67 with TESS and K2 [PDF]
Blue straggler stars (BSSs) are formed through mass transfers or mergers in binaries. The recent detections of white dwarf (WD) companions to BSSs in M67 suggested a mass transfer pathway of formation. In search of a close companion to five BSSs in M67
