Using ESO\u2019s Very Large Telescope (VLT) and VLT Interferometer (VLTI) in Chile, astronomers have directly observed two gas giants emerging from the planet-forming disk around a star known as WISPIT 2<\/a>, offering one of the clearest views yet of how a planetary system may form. The arrangement, marked by gaps and rings in the surrounding material, suggests that still more alien worlds could be assembling there.<\/p>\n

\u201cWISPIT 2 is the best look into our own past that we have to date,\u201d said Chloe Lawlor, a Ph.D. student at the University of Galway.<\/p>\n

\u201cWISPIT 2 gives us a critical laboratory not just to observe the formation of a single planet but an entire planetary system,\u201d added Dr. Christian Ginski, also from the University of Galway.<\/p>\n

\u201cWith such observations, astronomers aim to better understand how baby planetary systems develop into mature ones, like our own.\u201d<\/p>\n

The first protoplanet found in the WISPIT 2 system was detected a year ago, with a mass almost five times that of Jupiter.<\/p>\n

Named WISPIT 2b<\/a>, it orbits the central star at around 60 times the distance between Earth and the Sun.<\/p>\n

\u201cThis detection of a new world in formation really showed the amazing potential of our current instrumentation,\u201d said Richelle van Capelleveen, a Ph.D. student at Leiden Observatory.<\/p>\n

After an additional object was identified near the star, measurements made with VLT and VLTI telescopes confirmed its planetary nature.<\/p>\n

The newly-discovered planet, WISPIT 2c, is four times closer to the central star and is twice as massive as WISPIT 2b.<\/p>\n

Both planets are gas giants, like the outer planets in our Solar System.<\/p>\n

To confirm the existence of WISPIT 2c, the astronomers employed the SPHERE instrument on VLT.<\/p>\n

They then used the GRAVITY+ instrument on VLTI to confirm that the object was indeed a planet.<\/p>\n

\u201cCritically our study made use of the recent upgrade to GRAVITY+ without which we would not have been able to get such a clear detection of the planet so close to its star,\u201d said Dr. Guillaume Bourdarot, an astronomer at the Max Planck Institute for Extraterrestrial Physics.<\/p>\n

Both planets around WISPIT 2 appear in clear gaps within the disk of dust and gas circling the young star.<\/p>\n

These gaps result from each planet\u2019s development: particles in the disk accumulate, their gravity pulling in more material until an embryo planet forms.<\/p>\n

The remaining material, around each gap, creates distinctive dust rings in the disk.<\/p>\n

Besides the gaps that the two planets were found in, there is at least one smaller gap farther out in the WISPIT 2 disk.<\/p>\n

\u201cWe suspect there may be a third planet carving out this gap, potentially of Saturn mass owing to the gap\u2019s being much narrower and shallower,\u201d Lawlor said.<\/p>\n

The results<\/a> appear in the Astrophysical Journal Letters.<\/p>\n
