NGC 2547

NGC 2547 is a southern open cluster in Vela, discovered by Nicolas Louis de Lacaille in 1751[2][3] from South Africa.

[5] A study using Gaia DR2 data showed that NGC 2547 formed about 30 million years ago together with a new discovered star cluster, called [BBJ2018] 6.

It was suggested that all these clusters formed in a single event of triggered star formation.

[10] The system 2MASS J08090250-4858172, also called ID8 is located in NGC 2547 and showed substantial brightening of the debris disk at a wavelength of 3 to 5 micrometers, followed by a decay over a year.

These could be debris disks and the material could be orbiting close to the snow line of these stars, indicating that planet-formation is underway in these systems.
