Can Rocky Worlds Orbiting Red Dwarf Stars Maintain Atmospheres? A major collaboration between James Webb and Hubble Space Telescopes is now underway to study nine rocky exoplanets and their red dwarf host stars.
Can Rocky Worlds Orbiting Red Dwarf Stars Maintain Atmospheres?

My guess is they are all tidally locked to be within the habitual zone, making it less likely to be habitable. Not sure if that would prevent atmospheres though
I think the key to atmosphere is a combination of sufficient gravity to hold planetary-generated gasses to the rock and a magnetosphere that is powerful enough to shelter the gas from being swept away by solar winds.
I know that red dwarf stars are the most common in the galaxy. That probably is why they want to know more about how they affect planets in their orbit.. I’ll check the article and get back to you
Edit: “Can we accurately predict whether an exoplanet has an atmosphere based only on its gravity and the amount of high-energy light it receives from its star, or are there too many other variables to consider?”
They are studying red dwarf exoplanets to determine if the relationship can be used for prediction. Great! Now we just need to crack the code for traveling to them
