Key Takeaways
- Protoplanetary disks are formations of dust and gas that may lead to planet formation around young stars.
- The Webb GO 2562 program focuses on examining dust particles in these disks to understand early planet development.
- The Butterfly Star (IRAS 04302) is being studied using data from Webb's NIRCam and MIRI, combined with Hubble's optical information.
- A key feature of the Butterfly Star's disk is a dark dust lane that creates a butterfly-like appearance, obscuring some light from the central star.
- The program aims to investigate four edge-on protoplanetary disks, with the Butterfly Star being one of the targets.
Protoplanetary disks are swirling formations of dust and gas that orbit a young star. These disks hold the building blocks that may lead to the creation of planets and other celestial objects. The Webb GO 2562 program is focused on examining the dust particles within these disks to gain insights into the initial phases of planet development.
Observations of the Butterfly Star
Webb’s study of the disk surrounding IRAS 04302+2247, often referred to as IRAS 04302, is part of this initiative. Scientists merged data from Webb's NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) alongside Hubble’s optical information to create a clear image of this protoplanetary disk.
Unique Features in the Image
In the resulting image, a dark vertical dust lane is present at the center, obscuring some light from the young star located in the disk’s middle. On both sides of this shadowy lane are reflection nebulae. The overall arrangement of the star and its disk gives off a butterfly-like vibe, which is the reason behind the star's nickname, “Butterfly Star.”
Webb’s infrared technology enabled it to detect the small dust grains that reflect the light from IRAS 04302. These grains extend a significant distance from the disk's center. Hubble’s optical imaging concentrated on the dark dust lane along with the clusters and streams of gas surrounding it. The details from Hubble reveal that the star continues to draw in material while simultaneously ejecting jets and outflows.
Goals of the Webb GO 2562 Program
The Webb GO 2562 Program is designed to investigate four protoplanetary disks that are oriented edge-on to us. The disk of the Butterfly Star is merely one of these targets.
