Evidence for Jet/Outflow Shocks Heating the Environment Around the Class I Protostellar Source Elias 29: FAUST XXI
Yoko Oya, Eri Saiga, Anna Miotello +1
We have observed the late Class I protostellar source Elias~29 at a spatial-resolution of 70~au with the Atacama~Large~Millimeter/submillimeter~Array (ALMA) as part of the FAUST La…
Unveiling accretion in the massive YSO G033.3891. Spatial and kinematic constraints from the CO bandhead emission
E. Koumpia, D. Sun, M. Koutoulaki +4
The inner parts of the hot discs surrounding massive young stellar objects (MYSOs) are still barely explored due to observational limitations in terms of angular resolution, scarci…
The RMS survey: a census of massive YSO multiplicity in the -band
Robert G. Shenton, Rebecca J. Houghton, René D. Oudmaijer +4
Close to 100 per cent of massive stars are thought to be in binary systems. The multiplicity of massive stars seems to be intrinsically linked to their formation and evolution, and…
The sharpest view on the high-mass star-forming region S255IR. Near-InfraRed Adaptive Optics Imaging on the Outbursting Source NIRS3
R. Fedriani, A. Caratti o Garatti, R. Cesaroni +6
Massive stars have an impact on their surroundings from early in their formation until the end of their lives. However, very little is known about their formation. Episodic accreti…
First spatially resolved Na I and He I transitions towards an MYSO. Finding new tracers for the gaseous star/disc interface
Evgenia Koumpia, M. Koutoulaki, W. -J. de Wit +4
With steady observational advances, the formation of massive stars is being understood in more detail. Numerical models are converging on a scenario where accretion discs play a ke…
Observational constraints on disc sizes in protoplanetary discs in multiple systems in the Taurus region. II. Gas disc sizes
A. A. Rota, C. F. Manara, A. Miotello +13
The formation of multiple stellar systems is a natural by-product of the star-formation process, and its impact on the properties of protoplanetary discs and on the formation of pl…
RW Aur A : SpeX Spectral Evidence for Differentiated Planetesimal Formation, Migration and Destruction in an 3 Myr Old Excited CTTS System
C. M. Lisse, M. L. Sitko, S. J. Wolk +9
We present 2007 - 2020 SpeX VISNIR spectral monitoring of the highly variable RW Aur A CTTS. We find direct evidence for a highly excited, IR bright, asymmetric, and time variable…
A measure of the size of the magnetospheric accretion region in TW Hydrae
R. Garcia Lopez, A. Natta, A. Caratti o Garatti +69
Stars form by accreting material from their surrounding disks. There is a consensus that matter flowing through the disk is channelled onto the stellar surface by the stellar magne…
PENELLOPE: the ESO data legacy program to complement the Hubble UV Legacy Library of Young Stars (ULLYSES) I. Survey presentation and accretion properties of Orion OB1 and -Orionis
C. F. Manara, A. Frasca, L. Venuti +69
The evolution of young stars and disks is driven by the interplay of several processes, notably accretion and ejection of material. Critical to correctly describe the conditions of…
The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales
GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69
51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…
The GRAVITY young stellar object survey. II. First spatially resolved observations of the CO bandhead emission in a high-mass YSO
GRAVITY Collaboration, A. Caratti o Garatti, R. Fedriani +50
The inner regions of the discs of high-mass young stellar objects (HMYSOs) are still poorly known due to the small angular scales and the high visual extinction involved. We deploy…
Mirror, mirror on the outflow cavity wall. Near-infrared CO overtone disc emission of the high-mass YSO IRAS 11101-5829
R. Fedriani, A. Caratti o Garatti, M. Koutoulaki +7
Aims: The inner regions of high-mass protostars are often invisible in the near-infrared. We aim to investigate the inner gaseous disc of IRAS11101-5829 through scattered light fro…
An image of the dust sublimation region in the nucleus of NGC 1068
GRAVITY Collaboration, O. Pfuhl, R. Davies +40
We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very Large Telescope Inter…
The GRAVITY Young Stellar Object survey -- I. Probing the disks of Herbig Ae/Be stars in terrestrial orbits
K. Perraut, L. Labadie, B. Lazareff +69
The formation and the evolution of protoplanetary disks are important stages in the lifetime of stars. The processes of disk evolution and planet formation are intrinsically linked…
Exploring the dimming event of RW Aur A through multi-epoch VLT/X-Shooter spectroscopy
M. Koutoulaki, S. Facchini, C. F. Manara +6
RW Aur A is a CTTS that has suddenly undergone three major dimming events since 2010. We aim to understand the dimming properties, examine accretion variability, and derive the phy…
The circumstellar environment of HD50138 revealed by VLTI/AMBER at high angular resolution
M. Koutoulaki, R. Garcia Lopez, A. Natta +4
HD50138 is a Herbig B[e] star with a circumstellar disc detected at IR and mm wavelength. Its brightness makes it a good candidate for NIR interferometry observations. We aim to re…

J. Craig Wheeler, S. Nance, M. Diaz +6
In order to constrain the evolutionary state of the red supergiant Betelgeuse, we have produced a suite of models with ZAMS masses from 15 to 25 Msun in intervals of 1 Msun includi…
