We present the first far-UV (FUV) imaging results of the intermediate-age Galactic open cluster NGC 2818 that has a planetary nebula (PN) within the field using images taken from the Ultra Violet Imaging Telescope (UVIT) aboard AstroSat.

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 ...

The Origin of Young Stellar Populations in NGC 1783: Accretion of External Stars
The presence of young stellar populations in the Large Magellanic Cloud cluster NGC 1783 has caught significant attention, with suggestions ranging from it being a genuine secondary stellar generation to a population of blue straggler stars or simply ...

A rotation-based census of blue lurker candidates in open clusters
Aims. We have compiled a list of blue lurker (BL) candidates in open clusters using the available rotation catalogs. Blue lurkers are rejuvenated main-sequence stars hidden among normal main-sequence stars on color-magnitude diagrams of star clusters. In

Using data from Gaia Data Release 3 and Kepler/K2, we present a catalog of 16 open clusters with ages ranging from 4–4000 Myr that provides detailed information on membership, binary systems, and rotation. We assess the memberships in 5D phase space, and

Magnetic Field Amplification during Stellar Collisions between Low-mass Stars
Blue straggler stars in stellar clusters appear younger and bluer than other cluster members, offering a unique opportunity to understand the stellar dynamics and populations within their hosts.

Transitory Tidal Heating and Its Impact on Cluster Isochrones
The kinetic energy in tidal flows, when converted into heat, can affect the internal structure of a star and shift its location on a color–magnitude diagram from that of standard models.

Blue stragglers as the source of the high-velocity A stars
A quantitative estimate of the contribution of blue stragglers to the stellar population in the solar neighborhood is made, with particular attention to the spatial distribution of early-type stragglers at large distance from the Galactic plane. Blue stragglers are assumed to be created in the disk at a rate consistent with the empirical data from open
