Infrared spectroscopy of symbiotic stars . XII . The neutron star SyXB system 4 U 1700 + 24 = V 934

Editorial Dear Colleagues, It is a pleasure to present you the 259 issue of the AGB Newsletter. In case you wondered why Adam Ginsburg posted their paper on a protostellar disc, it is because the molecular species detected in that disc have previously only been seen in AGB star atmospheres. Congratulations to Andrea Chiavassa for his Habilitation thesis! Various workshops and schools are being organised: an evolved stars session at the European Week of Astronomy and Space Science in Lyon, a school on proposal preparation, data analysis and publication in the Slovak Republic, and a Cloudy workshop in Kentucky, USA. Last month’s Food for Thought asked ”What fraction of stars evolve as single stars all the way to the PN phase?” One response was received: Between 1% and 99%, but closer to 60% since at least 25% of all stars are multiple. Reactions to the question and this response remain welcome! The next issue is planned to be distributed around the 1 of March.
