Diana Dragomir is an assistant professor at the Department of Physics and Astronomy of the University of New Mexico. Her research focuses on the demographics and atmospheres of exoplanets smaller than Neptune. She is particularly interested in super-Earths and sub-Neptunes, planets with radii between those of the Earth and Neptune. A team of astronomers, including Dragomir of the University of New Mexico, has recently discovered a new exoplanet orbiting a nearby star. The newfound alien world, designated TOI-1231 b, is Neptune-sized, with a radius nearly four times greater than that of the Earth.
