small telescopes conference Slovakia September, 2018
Posted: Mon Sep 17, 2018 9:22 am
Observing techniques, instrumentation and science
for metre-class telescopes conference is organized in Slovakia next week
https://www.astro.sk/conferences/75AI20 ... rt=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
