HD276886: outburst?
Posted: Fri Feb 10, 2023 1:23 am
Dear all,
I haven't posted for a long time and I'm currently slowly coming back to astro after a quite long absence.
Yesterday was the first spectro night since about a year I think, and I started to point some Be stars, extracted from the ARAS-BeAM list of Be "to observe".
One of the targets was http://simbad.u-strasbg.fr/simbad/sim-i ... =HD+276886
And the spectrum I get is:

That is taken with a LISA (35um slit) mounted on a Newton 400F5
Since it is the first time I take spectra of Be stars I do not know what to expect but comparing with other Be spectra the Ha peak seems reeaaaally big. And the Hbeta region is also in emission. Is that an outburst?
Cheers,
Simon
