voici des résultats surprenants sur mon suivi de l'étoile de classe Be 25 Pegasus. Sur le montage gif, vous remarquerez les déplacements des pics d'émission des raies Ha et Hb pour la période du 3 août au 16 septembre 2022. J'ai quatre spectres pris les 3 et 15 août et 5 et 16 septembre. Remarquez lors du défilement des images, la stabilité des autres zones du spectre. Ce qui nous conforte dans la validité des résultats, vraiment le système Alpy 600 c'est un instrument bien conçu.
Si on se concentre sur les raies d'émission Ha et Hb et que je calcule les vitesses de dilatation (décalage vers le bleu) ou de contraction (décalage vers le rouge) j'obtiens les résultats suivants :
Hb
3 août dilatation à 357 km/s
15 août contraction à 92 Km/s
5 sept dilatation à 74 Km/s
16 sept dilatation à 185 Km/s
Ha
3 août dilatation à 174 km/s
15 août contraction à 138 Km/s
5 sept dilatation à 41 Km/s
16 sept dilatation à 91 Km/s

On a donc le même comportement des deux raies d'émission en Hb et Ha mais des lectures de vitesses plus élevées pour le Hb.

here are some surprising results on my tracking of the Be 25 Pegasus class star. On the attached gif montage, you will notice the displacements of the emission peaks of the Ha and Hb lines for the period from August 3 to September 16, 2022. I have four spectra taken on August 3 and 15 and September 5 and 16.Notice when scrolling through the images, the stability of the other areas of the spectrum. What consolidates us in the validity of the results, really the system Alpy 600 it is a well designed instrument. If we focus on the Ha and Hb emission lines and calculate the speeds of expansion (blue shift) or contraction (red shift) I get the following results:
Hb
August 3 dilation at 357 km/s
August 15 contraction at 92 Km/s
September 5 dilation at 74 Km/s
September 16 dilation at 185 Km/s
Ha
August 3 dilation at 174 km/s
August 15 contraction at 138 Km/s
September 5 dilation at 41 Km/s
September 16 dilation at 91 Km/s

We therefore have the same behavior of the two emission lines in Hb and Ha but higher speed readings for Hb.

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.
