Hello everyone! I’d like to advertise a recent paper: arxiv.org/abs/2505.04699.

Led by Lavinia Delfini, we use the Gaia XP spectra to derive accretion rates for 145 975 candidate YSO Hα emitters all-sky within 500 pc. We find a percentage of accretors of 70% at 2 Myr and 2.8% at 10 Myr.

Great talk today by Lucas Stapper on Herbig disks at the University of Milan! They are large, they are massive, they are gassy, and they are very interesting!

Richard Booth is offering a post-doc position to work with him in Leeds on protoplanetary discs and planet formation. jobs.leeds.ac.uk/Vacancy.aspx...

Great team! And great city! Richard is happy to chat with anyone interested about the role, Leeds, etc.

Are you interested in a postdoc at Leiden Observatory on exoplanet and planet formation research? Consider applying for the Oort fellowship! Applications should be submitted by December 15th. Please contact me if you're interested to have me as sponsor. jobregister.aas.org/ad/581f7e63

Gaia uncovers difference in B and Be star binarity at small... Be stars make up almost 20% of the B star population, and are rapidly rotating stars surrounded by a disc; however the origin of this rotation remains unclear. Mass transfer within close binaries...

We present a new work with a new insight to the Be phenomenon using astrometry. Led by Jonathan Dodd from the University of Leeds.

"Binary interaction via mass transfer causes the Be phenomenon, and triplicity plays a vital role on it"

Last day at the Joint ALMA Observatory. I can't believe 3 years have passed. I will miss Chile and living in Santiago. Now it is time to get ready for the next adventure at ESO Garching!

First post in this new space!

We have studied the clustering properties of forming stars from 1.5 to 20 solar masses as they are traced by the Gaia mission. We find there is an intermediate-mass range (4-10 solar mass) where stars are not that clustered.
