‘Detailed observations’: astro-tribal jargon? an astronomical filler phrase? a cognitive shortcut? a currency of prestige? or just communicative laziness that says very little?

Happy to share the European Space Agency @science.esa.int image release from our recent paper, which finds companions in the inner dust cavities of protoplanetary disks using data from the Gaia space telescope!

Gaia finds hints of planets in baby star systems

Fantastic results by @mvioque.bsky.social et al. This is an idea that we started working on a couple of years back - on time for Gaia DR4!

I think with "plane" they meant a trend in a "fundamental space" of parameters, rather than implying a flat structure. But I haven't read it in detail! Inclined planets are the best 🙌

(Re)-Defining Planets -- the Fundamental Plane of Planets 6000+ exoplanets are now detected using various techniques, with estimates of billions of planets existing in our Galaxy alone. They are called super-Earths, hot Earths, mini-Neptunes, hot Neptunes, s...

Planet = 'A celestial spherical object, bound to a star or unbound, that lies on the fundamental planetary plane, within a mass range between 0.02 EU to 13 JU'.

Interesting paper addressing taxonomy and definitions regarding planets, beyond the -arguably problematic- IAU definition.

Chilean delegation at #skao2025. With A. Garufi playing double agent for Italy and Chile.
I don't think I've been to an astronomy conference with so few Chileans.

Title slide with theee images of planetary disks from IR(?), mm/submm(ALMA), and cm (VLA)

Slide showing the observing gap (cm to km) in our understanding of planet formation.

Image of census of planetary disks in Taurus. Planetary disks are short lived and therefore rare.

First science talk at #skao2025 by Antonino Garufi about studying planet formation. Centimetre observations are critical to observing the growth of pebbles in planetary disks. 🧪 🔭 📡

A Multi-Wavelength Study of the Dynamic Environment surrounding the FUor V960 Mon The evolution of young stars and planet-forming environments is intrinsically linked to their nascent surroundings. This is particularly evident for FU Orionis (FUor) objects$-$a class of young protos...

New paper on #arXiv! We unveil the dynamic environment around the eruptive young star V960Mon, including signs of a fragmenting spiral arm, a new Class 0 protostar, and powerful outflows, a multi-wavelength look at planet formation in action. Led by Philipp Weber &

The Words Federal Agencies Are Discouraged From Using Under Trump Federal agencies have issued guidance to employees on hundreds of terms to limit or avoid using. An analysis of government websites shows many of the same words being removed.

This is why academics and universities need to speak up and push back, now: These Words Are Disappearing in the New Trump Administration www.nytimes.com/interactive/...

The centimeter emission from planet-forming disks in Taurus The last decade has witnessed remarkable advances in the characterization of the (sub-)millimeter emission from planet-forming disks. Instead, the study of the (sub-)centimeter emission has made more ...

Cool paper by Garufi et al today on arxiv. Expanding our knowledge of Taurus using cm wavelength. Surprisingly quite a large fraction of the emission is from dust and not only free free.

NASA's Hubble Finds Sizzling Details About Young Star FU Orionis - NASA Science In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 10...

"Shocking" results from Adolfo's team.
FU Ori keeps delivering amazing discoveries after >80 years of activity.

Rubin Observatory's telescope inside the observatory dome, with the night sky visible through the rectangular opening overhead. The short and squat teal telescope is viewed from a diagonal angle at ground level, pointed straight up and illuminated from the bottom.

✍️ Rubin #CommissioningNotes, entry 2️⃣: when you turn it on and it works 🤌

Initial tests with Rubin's test camera, ComCam, showed the telescope was already nearly aligned before even looking at the sky — a testament to decades of work! 🔭🧪

"Nature is telling us that it’s very easy for her to form planets, and that’s a slap in the face for astronomers because we still don’t know how they form,”

Beautiful piece on our latest discovery.
