SS433 microquasar spectrum (V1343 Aquilae) (Stephane Neveu)

SS433 microquasar spectrum (V1343 Aquilae)

The microquasar SS433 is an eclipsing X-ray binary system, with the primary being a stellar-mass black hole.
The compact central object is consuming the companion star which rapidly loses mass into an accretion disc formed around the central object. The accretion disc is subject to extreme heating as it spirals into the primary and this heating causes the accretion disc to produce opposing jets of hot hydrogen along the axis of rotation.
The animation made of 3 images - July 2022 (9, 23 and 30th) - show shifted emission lines (Hα+ and Hα-) around intense Hα (λ=6563 A).
The Hα+ and Hα- lines emitted by the object are the 2 components of a matter jet emitted by the micro quasar.
One of these components comes towards us (Hα-) the other moves away from us (Hα+).
These velocities vary due to the precession of the axis of rotation of the jet. We can roughly measure these shifts then the speed of the jet : from 10000 to 30 000 Km/s

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
