Scientists find green star that changes colour, Warwick University study says

LONDON: Science students are taught that stars have set colours. Red, orange and yellow stars are cooler, while hotter stars are white and blue. Scientists have now found stars that change colour like chameleons, and in colours that had never been thought of before.
A study by Warwick University has described stars that keep changing to green and pink. According to the researchers, these small stars are like chameleons.
Details of the study
The researchers said the colour of most white dwarf stars depends on temperature, but nobody had seen the process behind it. They said: “We found that such stars can change to colours that nobody had expected, and some truly surprised us.”
According to the research team, they discovered for the first time that white dwarf stars changed themselves into several colours. The team used data on 151 white dwarf stars and converted it into a simulation of colours as seen by human eyes.
A total of 146 stars appeared bright white, but the other five surprised the research team. According to the researchers, those stars can change to yellow, purple, pink and green.
The green star was named WD J1330.
