Wind Roche-lobe Overflow in Low-mass Binaries: Exploring the Origin of Rapidly Rotating Blue Lurkers
The Astrophysical JournalWind Roche-lobe overflow (WRLOF) is a mass-transfer mechanism proposed by Mohamed and Podsiadlowski for stellar binaries wherein the wind acceleration zone of the donor star exceeds its Roche-lobe radius, allowing stellar wind material to be transferred ...

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

S986 in M67: A Totally-Eclipsing Binary at the Cluster Turnoff
, 2003 We have discovered that the star S986 in the old open cluster M67 has detectable total eclipses of depth 0.08 mag for the primary eclipse and 0.011 mag for the secondary eclipse (in I only).

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.

Variables in Globular Cluster NGC 5024
, 2011 We present the results of a commissioning campaign to observe Galactic globular clusters for the search of microlensing events. The central 10' X 10' region of the globular cluster NGC 5024 was monitored using the 2-m Himalayan Chandra Telescope in R ...

HIP 8522: A Puzzling Young Solar Twin with the Lowest Detected Lithium Abundance
The Astrophysical JournalWe present HIP 8522, a young solar twin with the lowest detected lithium abundance, potentially a field blue straggler or the result of episodic early accretion. Its stellar parameters ( T _eff = 5729 ± 7 K, $\mathrm{log}\,g$ = 4.532 ± 0.016 dex, [Fe/H]

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.
