Expected Large Synoptic Survey Telescope (LSST) Yield of Eclipsing Binary Stars

, 2011
In this paper we estimate the Large Synoptic Survey Telescope (LSST) yield of eclipsing binary stars, which will survey ~20,000 square degrees of the southern sky during the period of 10 years in 6 photometric passbands to r ~ 24.5.

Data privacy model using blockchain reinforcement federated learning approach for scalable internet of medical things

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Internet of Medical Things (IoMT) has typical advancements in the healthcare sector with rapid potential proof for decentralised communication systems that have been applied for collecting and monitoring COVID‐19 patient data. Machine Learning algorithms typically use the risk score of each patient based on risk factors, which could help ...

The Triple System V1371 Tau: An Eclipsing Binary with an Outer Be Star

The Astrophysical Journal
Although triple systems are common, their orbital dynamics and stellar evolution remain poorly understood. We investigated the V1371 Tau system using TESS photometry, multiepoch spectroscopy, and recent interferometric data, confirming it as a rare ...

The occurrence of classical Cepheids in binary systems

, 2014
Classical Cepheids, like binary stars, are laboratories for stellar evolution and Cepheids in binary systems are especially powerful ones. About one-third of Galactic Cepheids are known to have companions and Cepheids in eclipsing binary systems have ...

Haunting the Historiography of Slaves in South Asia from the nineteenth century to the present

Gender &History, EarlyView.
ABSTRACT Using both English and Urdu‐language records, this article traces the career of a few African and Afro‐Asian women slaves in the household‐state of Awadh during the first half of the nineteenth century. Focusing on the same records, this article compares a master‐poet's recognition of the motherhood of the African and Afro‐Asian slaves to the ...

A Low Metallicity Massive Contact Binary Star System Candidate in WLM Identified by Hubble and James Webb Space Telescope Imaging

The Astrophysical Journal
We present archival Hubble Space Telescope (HST) and JWST ultraviolet through near-infrared time series photometric observations of a massive minimal-contact binary candidate in the metal-poor galaxy Wolf–Lundmark–Melotte ( Z  = 0.14 Z _⊙ ).

Queering Institutional Milestones in Elite Higher Education: Queer Perspectives on Princeton University and Coeducation (1960–1980)

Gender &History, EarlyView.
ABSTRACT A new archive of oral history interviews from LGBTQIA‐identified alumni, faculty and staff reveals the complex ways that queer and transgender students understood, experienced and remembered the long transition from single‐sex to coeducation at Princeton University.

Evidence for a Close-in Tertiary Orbiting around the Algol-type System HZ Dra with Tidal Splitting and Spots Activities

The Astrophysical Journal
We report a cyclic variation of the O − C diagram with a semiamplitude of 0.0033 days and a period of 1.05 yr for the pulsating eclipsing binary HZ Dra. The cyclic variation can be explained by the light travel-time effect via the presence of a close-in ...
