Researchers in Abu Dhabi are studying how a planet's relationship with its host star can affect its ability to support life.
A new study by NYU Abu Dhabi found that emissions from host stars can strip away the atmosphere of planets orbiting them. Scientists believe that planets with no atmosphere are uninhabitable.
Results of the study were published in the Monthly Notices of Royal Astronomical Society: Letters journal this month and led by research scientist Dr Dimitra Atri with involvement from graduate student Shane Carberry Mogan.
After looking at 493 host stars outside our solar system, it was found that extreme ultraviolet radiation and stellar flares from some categories of host stars can destroy the upper atmosphere of planets orbiting them.
"We have identified exoplanets in the M0 to M4 [host stars] category are least likely to be habitable, because their atmospheres will be completely eroded by extreme ultraviolet radiation," Dr Atri told The National.
So far, scientists have discovered 4,000 planets around more than 3,000 host stars, none of which have shown habitable conditions similar to Earth's.
To find distant planets that can support life, researchers look at planets in habitable zones known as the Goldilocks Zone. This is a zone where planets are not too close or too far from their host star, allowing it to sustain water.
For example, Earth is far enough from its host star, the Sun, to avoid radiation, yet close enough to stay warm.
“Given the close proximity of exoplanets to host stars, it is vital to understand how space weather events tied to those stars can affect the habitability of the exoplanet,” Dr Atri said.
His study showed that lighter stars that get less excessive radiation have more chances of having habitable planets orbiting them.
The findings could help scientists take a host star’s radiation levels into account when trying to determine an exoplanet’s ability to support life.
Dr Atri used data from Nasa’s Transiting Exoplanet Survey Satellite observatory for his study.
“The next research step would be to expand our data set to analyse stellar flares from a larger variety of stars to see the long-term effects of stellar activity, and to identify more potentially habitable exoplanets,” he said.
Dr Atri also hopes to use data from UAE’s Emirates Mars Mission to analyse how the Red Planet lost most of its atmosphere.
Scientists believe the planet once supported ancient life.

WHAT IS GRAPHENE?
It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were experimenting with sticky tape and graphite, the material used as lead in pencils.
Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But when they repeated the process many times, the flakes got thinner.
By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment led to graphene being isolated for the very first time.
In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics.

Tips for job-seekers
- Do not submit your application through the Easy Apply button on LinkedIn. Employers receive between 600 and 800 replies for each job advert on the platform. If you are the right fit for a job, connect to a relevant person in the company on LinkedIn and send them a direct message.
- Make sure you are an exact fit for the job advertised. If you are an HR manager with five years’ experience in retail and the job requires a similar candidate with five years’ experience in consumer, you should apply. But if you have no experience in HR, do not apply for the job.

The Bio
Favourite Emirati dish: I have so many because it has a lot of herbs and vegetables. Harees (oats with chicken) is one of them
Favourite place to go to: Dubai Mall because it has lots of sports shops.
Her motivation: My performance because I know that whatever I do, if I put the effort in, I’ll get results
During her free time: I like to drink coffee - a latte no sugar and no flavours. I do not like cold drinks
Pet peeve: That with every meal they give you a fries and Pepsi. That is so unhealthy
Advice to anyone who wants to be an ironman: Go for the goal. If you are consistent, you will get there. With the first one, it might not be what they want but they should start and just do it

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.
