Interestingly, a linear extrapolation from Cycles 1-4 (increasing about 400 proposals a Cycle) would also put us somewhere in the middle (2756) of the estimates shown!

Ah, interesting to know for the future! Alas we can't see dates for those but there must be a much longer early tail than we thought.

I've been trying this in Leiden too - but this looks like much more sophisticated analysis! We were working off of a start of 9549 since PID 9548 was awarded DDT time...

Wow, what a great image! Congrats to Richelle! With last week's 2MJ1612 it seems like accreting protoplanets are like buses: we wait 7 years since PDS70 and now two come along at once!

I'm surprised no one here has mentioned the new A&A page limit. I can only expect that what would have been large monolithic papers will be broken up, further boosting the number. It may also increase quality and brevity, making each review less demanding, but I'll be curious to see how it plays out

Thanks for being the one ray of sunshine in my otherwise gloomy inbox of rejection!

Never underestimate how hard this dilemma is to navigate... I spent around 3-4 months looking for the bug in our code a couple of years ago before finally deciding it was a real effect.

Of course, there was the time we forgot to ask them out their names on them and had the fun puzzle to try to match up more than 50 pairs, having to resort to forensic analysis of how they drew hands, feet etc etc if the picture had changed a lot.

Nice to see that some of our favourites are still on the website! chaosscience.org.uk/sponsors/#tr...

It was always an evening highlight to look at these back at the campsite and see what else changed (many fewer adjectives like "mad" and "evil", more "useful" or "anyone can be a scientist"!).

Ahh got it, thanks! Is there a reason there would only be an outflow from one source then? The discs look roughly equally bright on ALMA continuum? Presumably we can't get a good handle on their relative masses for such young sources though that know if that contributes...

Nice work by Isaac! I bookmarked it on arXiv this morning to have a closer look later, but what line is tracing the outflows here? Is that a streamer feeding Aa and is it connected to the outflow?

the isotopologues probe deeper in the disc, providing a truer picture of how much CO2 there is and if it is enhanced. But higher resolution images are needed to confirm if this is due to drift or can be explained with an as yet unresolved cavity. 4/4 @sierragrant.bsky.social @theschwarz.bsky.social

However the strong CO2 is particularly exciting, because we see not only CO2 itself but potentially two of its isotopologues - 13CO2 and CO18O (more tenatively) - where one of the atoms has been replaced by a rarer isotope. The shapes and relative strengths of the emission features imply that... 3/4

Marissa found that CX Tau is an example of the discs with weak water but strong CO2. The weakness of the water is more or less in line with what one expects for given the disc's low accretion rate, though there is still evidence for cold water strong emission which may be connected to drift. 2/4

JWST mostly sees warm gas in the inner regions if protoplanetary discs. These discs are where planets form and the inner regions are especially important for rocky planets like Earth. So with such data we hope to learn what the building blocks of Earthlike planets are made of - how much water etc?
