Planet monitoring LP 791-18d Using the satellite to survey transiting exoplanets TESS NASA and the Spitzer Space Telescope

Abu Dhabi, United Arab Emirates: A team of scientists led by a team of researchers at the University of Montreal has discovered an Earth-sized planet outside the solar system. Preliminary data indicates the possible occurrence of volcanic phenomena on the surface of the planet LP 791-18d To the degree similar to that witnessed by the moon Io, which revolves around Jupiter, which is the most space body in the solar system in terms of volcanic activity. The team includes research scientist Mohamed Ali Deeb of the NYU Abu Dhabi Center for Astrophysics, Objects and Planets.

The data collected by the Transiting Exoplanet Survey Satellite of the mission “TESSThe US Space Agency “NASA”, the “Spitzer” space telescope and a number of ground-based observatories have a fundamental role in discovering and studying the planet. Dr. Muhammad Ali Deeb led the research efforts related to the study of the orbits of the group of planets, and verified its long-term stability and the low probability of the existence of other hidden bodies of the same size within the group, based on not observing any fluctuation in the orbits of the currently known planets.

The researchers describe how the planet was discovered and studied in a paper published in the journal Nature titled “Transit of an Earth-sized, orbitally heated, temperate planet in front of a star.” M6. The planet was discovered in orbit around a red dwarf star at a distance of about 90 light-years in the southern “Crater” group. The size of the new planet is estimated to be almost the size of Earth and exceeds it in terms of weight. The group in question includes two other planets, namely LP 791-18b And LP 791-18 c. During the rotation of the newly discovered planet in its orbit, it passes near the planet LP 791-18 c The larger one, which leads to a change in its shape due to the effect of gravity and the friction of its internal components, resulting in a rise in temperature and volcanic phenomena on its surface.

The study also indicated that the planet LP 791-18d Tied bound, that is, it has one side that always faces the star of the group, while the other side remains in permanent darkness. With the possibility of volcanic events, tidal constraint that may contribute to the formation of an atmosphere is an additional factor that increases the possibility of water condensation on the dark side of the planet. Scientists are interested in this aspect because of the importance of the sustainability of liquid water, as it is one of the elements that make any planet habitable.

Planet included LP 791-18 c Recently on the NASA James Webb Space Telescope’s Watch List, the latest paper notes the significance of the planet’s inclusion LP 791-18d in the same list to verify its eligibility as a viable site.

According to researcher Muhammad Ali Deeb: “The discovery of an Earth-sized planet within the habitable zone with possible volcanic activity is an important step in the search for life outside the solar system. The next step is to study the planet with the James Webb space telescope to identify the components of its atmosphere.”
