Massive star cluster formation I. High star formation efficiency while resolving feedback of individual stars

Brooke Polak, Mordecai-Mark Mac Low, Ralf S. Klessen +11

The mode of star formation that results in the formation of globular clusters and young massive clusters is difficult to constrain through observations. We present models of massiv…

Collisional excitation of methyl (iso)cyanide by He atoms: rate coefficients and isomerism effects

M. Ben Khalifa, P. J. Dagdigian, J. Loreau

Among all closed-shell species observed in molecular clouds, molecules with C symmetry play a crucial role, as their rotational spectroscopy allows them to behave as a gas t…

Self-consistent dust and non-LTE line radiative transfer with SKIRT

Kosei Matsumoto, Peter Camps, Maarten Baes +4

We introduce Monte Carlo-based non-LTE line radiative transfer calculations in the 3D dust radiative transfer code SKIRT, which was originally set up as a dust radiative transfer c…

The EDIBLES survey VI. Searching for time variations of interstellar absorption features

Amin Farhang, Jonathan Smoker, Nick L. J. Cox +10

Interstellar lines observed toward stellar targets change slowly over long timescales, mainly due to the proper motion of the background target relative to the intervening clouds.…

The diverse chemistry of protoplanetary disks as revealed by JWST

Ewine F. van Dishoeck, S. Grant, B. Tabone +14

Early results from the JWST-MIRI guaranteed time programs on protostars (JOYS) and disks (MINDS) are presented. Thanks to the increased sensitivity, spectral and spatial resolution…

Discovering new B[e] supergiants and candidate Luminous Blue Variables in nearby galaxies

Grigoris Maravelias, Stephan de Wit, Alceste Z. Bonanos +3

Mass loss is one of the key parameters that determine stellar evolution. Despite the progress we have achieved over the last decades we still cannot match the observational derived…

Using the motion of S2 to constrain scalar clouds around SgrA*

GRAVITY Collaboration, A. Foschi, R. Abuter +67

The motion of S2, one of the stars closest to the Galactic Centre, has been measured accurately and used to study the compact object at the centre of the Milky Way. It is commonly…

Uncovering the stellar structure of the dusty star-forming galaxy GN20 at z=4.055 with MIRI/JWST

L. Colina, A. Crespo Gómez, J. Álvarez-Márquez +35

Luminous infrared galaxies at high redshifts (>4) include extreme starbursts that build their stellar mass over short periods of time (>100 Myr). These galaxies are considered t…

Sensitivity study of chemistry in AGB outflows using chemical kinetics

S. Maes, M. Van de Sande, T. Danilovich +2

Asymptotic Giant Branch (AGB) stars shed a significant amount of their mass in the form of a stellar wind, creating a vast circumstellar envelope (CSE). Owing to the ideal combinat…

Extinction towards the cluster R136 in the Large Magellanic Cloud: An extinction law from the near-infrared to the ultraviolet

Sarah A. Brands, Alex de Koter, Joachim M. Bestenlehner +4

The cluster R136 in the giant star-forming region 30 Doradus in the Large Magellanic Cloud (LMC) offers a unique opportunity to resolve a stellar population in a starburst-like env…

MIRI/JWST observations reveal an extremely obscured starburst in the z=6.9 system SPT0311-58

J. Álvarez-Márquez, A. Crespo Gómez, L. Colina +29

Using MIRI on-board JWST we present mid-infrared sub-arcsec imaging (MIRIM) and spectroscopy (MRS) of the hyperluminous infrared system SPT0311-58 at z=6.9. MIRI observations are c…
