Re: Suspected/Misclassified Symbiotics: spectra required
Hello everyone, I hope you are all doing well! Today, I have added 52! new literature candidates to the website: https://sirrah.troja.mff.cuni.cz/~merc/classification (to the table of classical symbiotic stars candidates; they all have status 'No spectrum'). Several of them are quite bright, some ar...

Re: WRAY 15-1167 outburst
Great job! It is the first confirmed outburst of this symbiotic star! The spectroscopic data confirm it is of a Z And-type. Thanks to Hamish Barker for notifying about this brightening and Pete and Olivier for obtaining the spectra. Amazing cooperation. The Atel with the summary of the results is av...

Re: Suspected/Misclassified Symbiotics: spectra required
Hello everyone, short update. Neither VX CrV nor V893 Cen show emission lines. VX CrV is a Mira pulsator and the spectrum was obtained close to the minimum. I suggest obtaining another spectrum around maximum (August 2022) to see if at least Balmer lines will appear and to be able to constrain the c...

Re: Suspected/Misclassified Symbiotics: spectra required
Hello everyone, today, I have included a new target to the list on the website (https://sirrah.troja.mff.cuni.cz/~merc/classification) - THA 15-31 (Sco). In the paper which appeared today on Arxiv, Munari et al. classified the object as a new accreting-only symbiotic star (see the paper here: https:...

Re: Suspected/Misclassified Symbiotics: spectra required
Hello everyone, thank you to Hamish for the suggestion to prepare the online list with the targets. I was thinking about it for a while because indeed it became quite difficult to track the status of the campaign stars here on the forum from my posts and lists. Yesterday/today I have prepared a webs...

Gaia19bpg
Hello everyone, I am resubmitting here my post from the forum thread on the suspected and misclassified symbiotics as it seems that the object is very interesting and its spectroscopic observation might be time-critical. The working hypothesis is, that the object might be a symbiotic nova or a symbi...

Re: Suspected/Misclassified Symbiotics: spectra required
Hubert, thank you for obtaining the spectrum of the target. Would you be so kind to confirm, that you observed TYC-1371-69-1 and not TYC-1371-69-6 mentioned in your post? I am just checking to be sure, I was not able to find any star with the designation TYC-1371-69-6 in the SIMBAD, so I think this ...

Re: Suspected/Misclassified Symbiotics: spectra required
Let me also inform you, that the paper on Hen 3-860, the new southern eclipsing symbiotic star has been accepted in the Monthly Notices of the Royal Astronomical Society and is available on arXiv since today: https://arxiv.org/abs/2111.14975. The spectra obtained by Pete and Terry have been used in ...

Re: Suspected/Misclassified Symbiotics: spectra required
Hi Pete, thank you for your checking the guider image of V618 Sgr. That would mean, that the spectral appearance of V618 Sgr changes significantly with time, depending on the brightness (comparing Terry's, yours, and Kilkenny's 1988 spectrum). That is very interesting! I definitely suggest obtaining...

Re: Suspected/Misclassified Symbiotics: spectra required
I would like to add one more target to the list. I received some data from colleagues from Hungary this week. They study young stellar objects, but this one might be a symbiotic star. We already have two low-res optical spectra, one medium-res spectrum covering Halpha, IR spectra, but to confirm eit...
