A frozen super-Earth orbiting a star at the bottom of the Main Sequence [PDF]

open access: yes, 2012
We observed the microlensing event MOA-2007-BLG-192 at high angular resolution in JHKs with the NACO adaptive optics system on the VLT while the object was still amplified by a factor 1.23 and then at baseline 18 months later.

A specimen of little bush moa Anomalopteryx didiformis (Owen, 1844), Emeidae Bonaparte, 1854 from the National Museum of Natural History, Sofia

open access: yesHistoria Naturalis Bulgarica, 2018
A complete right tarsometatarsus from an unknown site of New Zealand was identified as little bush moa (Anomalopteryx didiformis (Owen, 1844)), possibly an adult male individual.

Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events [PDF]

open access: yes, 2009
To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of lensing light curves.

Candidate Brown-dwarf Microlensing Events with Very Short Timescales and Small Angular Einstein Radii [PDF]

open access: yes, 2019
Short-timescale microlensing events are likely to be produced by substellar brown dwarfs (BDs), but it is difficult to securely identify BD lenses based on only event timescales t_E because short-timescale events can also be produced by stellar lenses ...

暂态冲击负荷下MOA热散逸特性及影响因素研究

open access: yesDianci bileiqi, 2021
通过多起无间隙金属氧化物避雷器(以下简称MOA)事故的分析和研究,发现热崩溃在MOA损坏事故中占据很高比例。运行条件下,在MOA承受冲击负荷的过程中若发热高于散热则电阻片温度会累积升高,最终导致MOA热崩溃。MOA呈现的热散逸特性与暂态冲击负荷、MOA结构、元件材料、荷电率等因素有关,因此研究MOA的热散逸性及影响因素对MOA的设计和安全运行具有重要意义。本研究以典型35 kV复合外套MOA和瓷外套MOA为例,从暂态冲击负荷、MOA结构、荷电率以及表面污秽几个方面对MOA热散逸特性展开研究 ...
