A Analysis of the Light and Radial Velocity Curves of do CAS [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2000
DO Cas is a short period (P=0.68day) eclipsing binary star and is classified as a near-contact binary by Shaw (1990). There is no published radial velocity curve for this short period binary after Mannino (1958).

The structure equations of contact binaries [PDF]

open access: yesAstronomy & Astrophysics, 2002
The structure equations of contact binaries are discussed. An equation for the transfer of mass between the com- ponents is derived. Serious uncertainties concern only the transfer of energy. They are expressed as unknown functions. An evolution code for contact binaries is presented.

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

open access: yesAdvanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

HL Aurigae: A near-contact binary system

open access: yes, 1996
. Photoelectric observations of HL Aur were carried out with the 60 cm reflector of Beijing Astronomical Observatory in 1990 and 1994, and the rst photoelectric BV light curves were obtained along with a newly derived ephemeris.

GY Tel: a new thermally decoupled near contact binary system [PDF]

open access: yes, 2022
GY Tel is a short period (0.446 d) eclipsing binary system of 12th magnitude showing a large difference(0.85 mag) in the depths of minima. The first UBV observations obtained at Bosque Alegre (Córdoba) and at CASLEO (San Juan) are presented.

XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion

open access: yesAdvanced Functional Materials, EarlyView.
Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...

Contact posets [PDF]

open access: yes, 2023
We study contact posets and show that every contact poset can be embedded into a Boolean poset with overlap contact relation. Contact posets and (nonadditive) contact semilattices have the superamalgamation property, Fra\"\i ss\'e limits and model ...

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

open access: yesThe 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 _⊙ ).

Formation and Evolution of Contact Binaries [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
describe a series of processes, including hierarchical fragmentation, gravitational scattering, Kozai cycles within triple systems, tidal friction and magnetic braking, that I believe are responsible for producing the modest but significant fraction of stars that are observed as contact binaries. I also discuss further processes, namely heat transport,
