👁️ International research, with the participation of #IACastrofísica, finds an Earth-sized exoplanet potentially covered with volcanoes. Called LP 791-18 d, the geological activity could provide it with an atmosphere.

A fantastic group of researchers together working on the design the future #ANDES spectrograph for the future #eso #ELT telescope (just a sub-section of the team). With this ambitious instrument we will study the atmospheres of nearby Earth-like planets, such as Proxima b

Esta semana, en el espacio de cooperación tecnológica #IACTEC del #IACastrofísica, se ha celebrado la reunión del proyecto #ANDES, un espectrógrafo de alta resolución que se instalará en el telescopio #ELT de @ESO. Participan en el consorcio más de 30 instituciones de 14 países.

We are very happy to release today a very insteresting paper lead by our colleague Susana Barros (from @IAstroPT) on a five (5!!) planets system with three of them having sub-Earth (sub-Earth!!) masses. A few ideas on this great #ESPRESSO discovery: 🧵👇

The study was published in Science last week. You can find the IAC press release, and a link to the article, here https://t.co/zJp0QqwVdS

Is not everyday that we get an article with the potential of reframing our understanding of exoplanets. "Density, not radius, separates rocky and water-rich small planets orbiting M dwarf stars" by Rafael Luque and Enríc Pallé (https://t.co/z6AHgi7IdL)

[Exoplanets IAC @exoplanets_iac]

In fact, the usually assumed radius valley is more likely a density gap that separates rocky planets from water-rich exoplanets. This conclusion agrees with formation models: Rocky planets form within the snow line, while water-rich worlds form outside it and later migrate inward

A study, led entirely by researchers Rafael Luque, from @UChicago and @iaa_csic, and Enric Pallé, from #IACastrofísica and @ULL, confirms that "water worlds" could be as common as Earths.

This account has been silent, but the ESPRESSO team hasn't! On the past months we've published some results that might be of your interest. Let's start with the transmission spectroscopy of MASCARA-1b, showcasing what happens when the planet path overlaps with the doppler shadow
