The secondary star and distance of the polar V1309 Ori [PDF]

, 2006
The first phase-resolved JHK light curves of the eclipsing polar (AM Herculis binary) V1309 Ori are presented and interpreted. We separate the contributions from the secondary star and from other sources with the aim of determining a photometric distance.

Green Synthesis of Highly Luminescent Carbon Quantum Dots from Lemon Juice

Journal of Nanotechnology, 2019
Highly luminescent carbon dots (C-dots) were synthesized by the one-pot simple hydrothermal method directly from lemon juice using different temperatures, time, aging of precursors, and diluted solvents to control the luminescence of C‐dots. The obtained
