However, the star is only 1.3% as luminous as the sun. Therefore, it's probably not nearly as hot as you'd think...may well be similar to Earth in temperature.
Not similar to earth temps. Red dwarfs are generally thought to have surface temps of about 4,000 degrees or less. Cool as far as star temps go. I think the article states it is believed that this specific planet has surface temps of about 300 degrees.
