原文:Doomed Star Eta Carinae Image Credit: NASA, ESA, Hubble; Processing & License: Judy Schmidt Explanation: Eta Carinae may be about to explode. But no one knows when – it may be next year, it may be one million years from now. Eta Carinae’s mass – about 100 times greater than ...
As possibly the galaxy"s (银河) most massive star, Eta Carinae is now engaging in some very unusual behaviour. Australian astronomers, being in the Southern Hemisphere (半球), are able to observe it clearly.In the 19th century, Eta Carinae was for a time the third brightest star in the ...
stars : individual (eta Carinae) techniques : spectroscopicX-rays : starsWe present XMM-Newton observations of the luminous star Eta Carinae, including a high resolution soft X-ray spectrum of the surrounding nebula obtained with the Reflection Grating Spectrometer. The EPIC image of the field ...
NuSTAR发射于2012年,它可以将比以往任何望远镜更大的能量聚焦到x射线上。该研究小组利用最新获取的和存档的数据,研究了2014年3月至2016年6月期间获得的新星观测数据,以及同期欧洲航天局(European Space Agency)的XMM-Newton卫星的低能量x射线观测数据。 Eta Carinae的低能量或软x射线来自碰撞恒星风的交界面,那里的温...

It pumps out more than 5 million times the energy than the Sun does, but it and its companion star hide inside a double-dumbbell of dust and gas called the Homunculus Nebula. 机译:寻找巨大,不稳定的恒星Eta(η)Carinae的克隆的天文学家可能在其他星系中发现了五个。埃塔汽车(Eta Car)是银河系...
This spectacular panoramic view combines a new image of the field around the Wolf–Rayet star WR 22 in the Carina Nebula (right) with an earlier picture of the region around the unique star Eta Carinae in the heart of the nebula (left). The picture was created from images taken with the...
The shocks from the Eta Carinae star and the companion star can accelerate particles to different energies depending on the different conditions determined by the parameters of the stars. The lack of strong GeV gamma-ray variability with the period of the binary system can be also understood in ...
