The Carmen Project increases the number of known exoplanets near the Sun | Urania

20,000 observations have been announced, resulting in the discovery of 59 planets near the solar system. The study, which was led by Spanish and German institutions, is published in the journal Astronomy and Astrophysics.

design Carmen just published data from nearly 20,000 observations made between 2016 and 2020 for a sample of 362 close relatives. M dwarfs.. The project uses the CARMENES tool, spectrometer Optical and infrared, located at the Calar Alto Observatory, which is intended for research outer planets Similar to the land (rocky and moderate) located in environmental surroundings Their star, that is, the ability to have liquid water on their surface.

a job published in Astronomy and Astrophysics is the 100th paper prepared by the CARMENES consortium, which shows how successful the project has been in providing information about Earth-like exoplanets and their stars. Since its inception, Carmen has re-analyzed 17 known planets and discovered and confirmed 59 new planets in close proximity to our own. Solar Systemmany of which are potentially habitable explains Ignasi Ribas, director of the Institute of Space Studies of Catalonia (IEEC) and first author of this recently published paper.

Carmen observed nearly half of all nearby M dwarfs (only some of them can be observed from the Southern Hemisphere) and doubled the number of known exoplanets around them. In addition, the spectra obtained provide very valuable information, for example on the atmospheres of stars and their planets. It is hoped that with the publication of this first large dataset, the scientific community will analyze it and be able to increase its scientific output. The Carmen Project will continue the current series of observations through the end of 2023.
