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 ...

The frequency of snowline-region planets from four-years of OGLE-MOA-Wise second-generation microlensing. [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2015
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 deg2 of the Galactic bulge by the OGLE, MOA, and Wise microlensing surveys.

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.

On the age of Galactic bulge microlensed dwarf and subgiant stars [PDF]

open access: yes, 2015
Recent results by Bensby and collaborators on the ages of microlensed stars in the Galactic bulge have challenged the picture of an exclusively old stellar population. However, these age estimates have not been independently confirmed.
