Photometric Studies of the Contact Binary BV Draconis [PDF]
Journal of Astronomy and Space Sciences, 1999 We performed CCD photometric observations of W UMa type contact binary BV Dra during eight nights from May 1996 to June 1999 using 61cm telescope at Sobaeksan Optical Astronomy Observatory, and completed BVR light curves of the system.

SDSS J001641-000925: THE FIRST STABLE RED DWARF CONTACT BINARY WITH A CLOSE-IN STELLAR COMPANION
, 2015 SDSS J001641-000925 is the first red dwarf contact binary star with an orbital period of 0.19856 days that is one of the shortest known periods among M-dwarf binary systems. The orbital period was detected to be decreasing rapidly at a rate of .

Photometric investigation of the K-type extremely shallow contact binary V1799 Orion [PDF]
, 2014 New multi-color light curves of the very short period K-type eclipsing binary V1799 Ori were obtained and analyzed with the Wilson-Devinney code. The photometric solutions reveal that the system is a W-type shallow-contact binary with a mass ratio of q =

Advanced Functional Materials, EarlyView.Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Orbital Modulation Induced by a Third Component in the Overcontact Binary V0554 Dra
The Astrophysical JournalWe present the first comprehensive photometric and spectroscopic analysis of the overcontact eclipsing binary V0554 Dra. By simultaneously modeling multiband light curves and radial velocity data using the Wilson–Devinney code, we determine that the ...

New Photometric Investigation of the Solar-Type Shallow-Contact Binary HH Bootis
Advances in Astronomy, 2019 The short-period solar-type contact binary HH Boo was monitored photometrically for about 8 years. It is found that the CCD light curves in the B, V, R, and I bands obtained in 2010 are symmetric, while the multicolor light curves observed in 2011 and ...

Design of Terpene‐Based Eco‐Friendly Solution Process for High‐Performance Organic Solar Cells
Advanced Functional Materials, EarlyView.High‐performance, terpene‐processed organic solar cells (OSCs) by designing a new green co‐solvent system consisting of eucalyptol (Eu) and 2‐methyltetrahydrofuran (MeTHF) are developed. The OSCs processed from the optimal ratio of Eu and MeTHF achieve the highest power conversion efficiency (PCE) value of 17.3% reported to date for terpene‐processed ...

A Application of WD Model to EB Type Contact Binary System [PDF]
Journal of Astronomy and Space Sciences, 2000 The EB type contact binaries show large temperature difference ( T 1,000K) between two components. Thus we have modified the mode 3 of the WD program to adjust albedos, limb darkening coefficients and gravity darkening exponents for both components of ...
