Binarity, outflows and disks in young stellar objects: the case of HH 250
Abstract:
Binary stars, a common outcome of the star formation process, are particularly interesting among young stellar objects as probes of the early dynamical evolution of multiple stellar systems. Many among those display some of the observational manifestations of stellar youth, such as evidence for circumstellar disks and envelopes, accretion, and outflows, but few show most or all of those features at once. I will introduce the HH 250 system, a Herbig-Haro object powered by a binary star, which is one of just a handful of examples in which we can observe both components of the central binary, measure the spectral energy distribution of their respective circumstellar disks, determine the proper motion of the Herbig-Haro object, and find evidence of a circumbinary disk.

Big thank you to @MartinaPQuinn of @helloalicepr for moderating the discussion, and of course to our panel @NeasaMcG @CormacORafferty and @laoneill111
@CormacORafferty "to cut yourself off from fundamental research means you could miss out on some of the biggest ideas"
@laoneill "it's our job as researchers to keep reminding governments how important basic research is" "For Dev basic research being carried out in Ireland was a badge of pride"
@NeasaMcG Schrödinger's work in causality was not well received by the religious authorities at the time At the same time DIAS did have Catholic priests working on research projects in the early days, so there was not the conflict you might think between science and religion
@laoneill111 Schrödinger was very popular in social circles in Dublin, a bit of a renaissance man
@CormacORafferty Schrödinger was gifted at explaining difficult concepts
@CormacORafferty on how unsuccessful work, in Schrödinger's case, unified field theory, is just as important part of science. And no one has managed to crack it yet! And not forgetting the cat
@laoneill111 how Schrödinger's book inspired scientists to change fields and result in the finding of the double helix.
@NeasaMcG explaining how DIAS came about and how Schrödinger was attracted to Ireland #DIASdiscovers
Panel Discussion getting underway! @laoneill111 @CormacORafferty @NeasaMcG @MartinaPQuinn
