Observing techniques, instrumentation and science
for metre-class telescopes conference is organized in Slovakia next week

https://www.astro.sk/conferences/75AI2018/index.php?part=program

I'm invited to give a talk about eruptive stars monitoring by ARAS observers
A nice aknowledgment to our collective work

Abstract:
Spectroscopic Monitoring of Eruptive Stars and the ARAS database
F.Teyssier
ARAS ( Astronomical Ring for Amateur Spectroscopy )
Spectroscopicmonitoring of eruptive stars (e.g. symbiotic binaries, classical novae) by amateurs around
the world, in both the northern and southern hemispheres, is a fundamental activity of ARAS (Astro-
nomical Ring for Amateur Spectroscopy) initiative. The group of volunteers demonstrates what can be
accomplished with a network of independent, very small telescopes (from 20 to 60 cm), furnished with
spectrographs of different resolution, from 500 to 15000, and covering the range from 3600 to nearly
8000°A. Acquisition, reduction and analysis of the spectra will be described.
The observing program concentrates on bright symbiotic stars (52, to date) and novae (34, to date).
The main features of the ARAS activity are rapid response to alerts, long term monitoring and high
cadence. A part of the program involves collaborations based on requests from professional teams (e.g.
CH Cyg, AG Dra, R Aqr, SU Lyn, V339 Del) for long time monitoring or specific events. Some examples
of the evolution of basic observational parameters along outbursts and/or as a function of the orbital
phase (e.g. radial velocities, equivalent widths or lines profiles) are presented. The spectra are gathered
in the open access Eruptive Stars Database that has been used for several publications by professional
teams.

Jaroslav Merc will talk about collaboration with ARAS group on symbiotic stars monitoring

It will be also a pleasure to meet Ernst and Thilo

Hello from Slovakia,

The conference began yesterday.

Very interesting on many subjects. Some of the presentations are already on-line: https://www.astro.sk/conferences/75AI2018/index.php?part=program

ARAS group on the spotlight:

Drahomír Chochol (with Joan Guarro as co-autheur): Optical photometry and spectroscopy of V612 Sct: slow classical nova with rebrightenings (B02) [Nova Sct 2017]
Augustín Skopal: Studying symbiotic stars and classical nova outbursts with small telescopes (B07) [emphasizing the importance of ARAS observation]
Rudolf Gàlis : The current active stage of the symbiotic system AG Draconis (B08) [idem] https://www.astro.sk/conferences/75AI2018/talks/B08.pdf
Jaroslav Merc: Study of long-term spectroscopic variability of symbiotic stars based on observations of the ARAS Group (B13) https://www.astro.sk/conferences/75AI2018/talks/B13.pdf
François Teyssier: Spectroscopic Monitoring of Eruptive Stars and the ARAS database (B12) https://www.astro.sk/conferences/75AI2018/talks/B12.pdf

and 2 posters:
Augustin Skopal: First glance to the recently discovered symbiotic star HBHA 1704-05 with Christian Buil and Paolo Berardi as co-authors
Natalia Shagatova : H alpha orbital variations of the symbiotic star EG And from optical spectroscopy with F. Teyssier as co-author
(not yet on-line)

Excellent synergies and a clear demonstration of the importance of ARAS group for eruptive stars monitoring, thanks to the serious and continuous involvement of number of observers

All the best,

Merci beaucoup,Umberto,
Mais seulement d'une partie du travail.
C'est aussi et surtout, à mes yeux, la reconnaissance du travail acharné, sur une longue durée, de nombreux observateurs (dont tu fais partie)
We acknowledge with thanks …
the dedicated observers of the Astronomical Ring for Access to Spectroscopy (ARAS) group
for their tireless and selfless efforts.
Ackermann & al., 2014
All the best!
