Comparaison spectres Denebola et T Crb

Pour clarifier le spectre de T CRB je l'ai comparé avec le spectre de Denebola que j'ai pris le même soir (7 avril 2024). On voit clairement les raies d'absorption de la série Balmer sur le spectre de Denebola et si on compare avec le spectre de T Crb on constate qu'en position Ha et Hb il y a des raies d'émission. J'ai ajouté le spectre de l'étoile HD167006 (extrait de la banque de spectres Miles) qui est de la même classe que T Crb mais qui n'a pas de disque d'accrétion donc aucune raies d'émission en Ha et Hb. Incroyable l'information qu'on capte de cette lumière d'étoile qui a voyagé pendant des années avant d'être captée par mon spectroscope!

To clarify the T CRB spectrum I compared it with the Denebola spectrum that I took the same evening (April 7, 2024). We clearly see the absorption lines of the Balmer series on the Denebola spectrum and if we compare with the spectrum of T Crb we see that in position Ha and Hb there are emission lines. I added the spectrum of the star HD167006 (extracted from the Miles spectrum bank) which is of the same class as T Crb but which does not have an accretion disk therefore no emission lines in Ha and Hb . Incredible the information we capture from this starlight which traveled for years before being captured by my spectroscope!

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.
