The Astrophysical JournalWe have analyzed Chandra and Suzaku observations of the globular cluster Terzan 6, made when the recurrent transient GRS 1747–312 was in quiescence. Our analysis reveals the presence of a second eclipsing, bursting neutron star low-mass X-ray binary in ...

Formation Channels for Blue Straggler Stars [PDF]
, 2014 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 ...

Dynamics of Purification in Cu2O
physica status solidi (b), EarlyView.Rydberg excitons in Cu2O have been shown to be highly efficient in neutralizing and screening charged impurities, which is referred to as purification. In this manuscript, the dynamics of the purification process are investigated under varying probe exciton‐ and plasma density. The transient absorption of Rydberg excitons is analyzed and five different

The Astronomical JournalWe investigate the evolutionary stages of four open clusters—Berkeley 39, Collinder 261, NGC 6819, and NGC 7789—of ages ranging from 1.6 to 6 Gyr. These clusters have previously been classified into dynamically young and intermediate age groups based on ...

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study presents a successful numerical simulation of cyclone Leslie (2018), using WRF‐ARW v4.5.1. Several mesoscale dynamics were identified indicative of the occurrence of sting jet and cold conveyor belt, which potentiated the record‐breaking winds in central Portugal.

Stellar Spin-down in Post-mass-transfer Binary Systems
The Astrophysical JournalMotivated by measurements of the rotation speed of accretor stars in post-mass-transfer (post-MT) systems, we investigate how magnetic braking affects the spin-down of individual stars during binary evolution with the MESAbinary module.

Giant Tunability of Individual Magnetic Skyrmion Size via an Oscillating Local Magnetic Field
Rare Metals, EarlyView.ABSTRACT Magnetic skyrmions hold great promise as memory and computing elements in future spintronic devices. Despite the demonstration of various devices, techniques for addressable and high‐precision manipulation of individual skyrmions remain scarce.
