Cracking open the "dragon egg": ALMA 1.3mm observations of a compact, young high-mass core candidate at 30mas resolution
A. T. Barnes, J. D. Henshaw, Á. Sánchez-Monge +14
Massive prestellar cores are a central assumption of core-accretion models of high-mass star formation, yet convincing observational examples remain rare. The "dragon egg" (C2c1a)…
Unveiling Complex Chemistry in Planet-forming Disks with the SKAO
Linda Podio, Lisa Giani, Catherine Walsh +38
The chemical composition of planets is inherited from that of the natal protoplanetary disk at the time of planet formation. In recent years, we have made huge progress in characte…
Jets and Outflows in Young Stellar Objects with the SKAO
Giovanni Sabatini, Gemma Busquet, Carlos Carrasco-González +48
Jets and outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting s…
Resolving the smallest scales of massive star formation: A case for next-generation thermal-infrared interferometers
Emma Bordier, Evgenia Koumpia, Lucas Labadie +3
This white paper was submitted to the European Southern Observatory (ESO) as part of the "Expanding horizons: transforming astronomy in the 2040s" call. Understanding how massive s…
Class I CH3OH Maser Emission from Bar-Driven Inflow Colliding with the Central Molecular Zone
V. S. Veena, W. -J. Kim, P. Schilke +9
The Central Molecular Zone of the Milky Way is shaped by the interplay of bar-driven inflows, shocks, and star formation. At Galactic longitude l=1.3, gas inflowing along the near-…
Physical characterization and modeling of candidate Hyper-Compact HII Regions
I. T. Rodríguez-Esnard, S. Kurtz, J. D. Pandian +4
Hypercompact HII regions (HC) are regions of ionized gas associated with the early stages of high-mass star formation. With the aim of better understanding their characteristics, w…
The GUAPOS project -- VII: Physical structure and molecular environment of the G31.41+0.31 HII region
R. Cesaroni, M. T. Beltrán, V. M. Rivilla +6
Ionised regions around OB-type stars are formed at an early stage of their evolution and are important to investigate the formation process of these objects. However, so far only f…
Unveiling the First O-Type Bloated Star Candidate through ALMA and EVLA Observations
Rakesh Pandey, Aina Palau, Alvaro Sánchez-Monge +5
We investigate the circumstellar environment of the O-type bloated star candidate IRAS 19520+2759 (I19520) using high-resolution observations from the Atacama Large Millimeter/subm…
Rotation and stability of the circumnuclear gas disk in the Galactic Center potential by the ALMA CMZ Exploration Survey (ACES)
Yoshiaki Sofue, Steven N. Longmore, Daniel Walker +26
We investigated the gravitational potential and mass distribution in the Galactic Center by examining the morphology and kinematics of the circumnuclear gaseous disk revealed by th…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. V. Chemical composition gradients as a function of the galactocentric radius
D. Gigli, F. Fontani, L. Colzi +4
The outer Galaxy is characterized by a lower metallicity than regions near the Sun, suggesting differences in the formation and survival of molecules in star-forming regions. To un…
First detection of variable radio emission originating from the infant planetary system V1298 Tau
M. Damasso, O. Morata, S. Kaur +13
V1298 Tau is a very young and magnetically active star which hosts a benchmark multi-planetary system to study planet formation and evolutionary history at the earliest stages. We…
Mother of Dragons: A Massive, quiescent core in the dragon cloud (IRDC G028.37+00.07)
A. T. Barnes, J. Liu, Q. Zhang +15
Context: Core accretion models of massive star formation require the existence of massive, starless cores within molecular clouds. Yet, only a small number of candidates for such t…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. I. Organic molecules and tracers of star-formation activity
F. Fontani, L. Colzi, L. Bizzocchi +8
The outer Galaxy is an environment with metallicity lower than the Solar one. Because of this, the formation and survival of molecules in star-forming regions located in the inner…
