Dynamical Cluster Assembly Framework (D-CAF): The Link Between Star Cluster Formation and Expansion Rates
Juan P. Farias, Alison Sills
We introduce the Dynamical Cluster Assembly Framework (D-CAF), an AMUSE-based framework designed to connect embedded star formation histories to the dynamical evolution of young st…
SPYGLASS. VII-B. Tracing the Fragments of Massive Star Formation Using Low-Mass Associations
Ronan Kerr, Adam L. Kraus, Jonathan C. Tan +6
New observations from the Gaia spacecraft have traced an emerging demographic of low-mass associations disconnected from larger associations or GMCs. The first of these association…
Star cluster formation from turbulent clumps. V. Stellar clustering around massive stars
Aayush Gautam, Juan P. Farias, Jonathan C. Tan
Massive stars (> 8 ) are known to have high degrees of multiplicity, e.g., with about 60% in triples or higher-order multiples. Such high levels of multiplicity may arise…
Star cluster formation from turbulent clumps. IV. Protoplanetary disc evolution
Aayush Gautam, Juan P. Farias, Jonathan C. Tan
Most stars are born in the crowded environments of gradually forming star clusters. Dynamical interactions between close-passing stars and the evolving UV radiation fields from pro…
Low-mass Runaways from the Orion Nebula Cluster -- Kinematic Age Constraints on Star Cluster Formation
Muhammad Fajrin, Joseph J. Armstrong, Jonathan C. Tan +2
In their early, formative stages star clusters can undergo rapid dynamical evolution leading to strong gravitational interactions and ejection of "runaway" stars at high velocities…
Near-Infrared Observations of Outflows and YSOs in the Massive Star-Forming Region AFGL 5180
S. Crowe, R. Fedriani, J. C. Tan +30
Methods: Broad- and narrow-band imaging of AFGL 5180 was made in the NIR with the LBT, in both seeing-limited ($\sim0.5\arcsec$) and high angular resolution ($\sim0.09\arcsec$) Ada…
Stellar Populations in STARFORGE: The Origin and Evolution of Star Clusters and Associations
Juan P. Farias, Stella S. R. Offner, Michael Y. Grudić +2
Most stars form in highly clustered environments within molecular clouds, but eventually disperse into the distributed stellar field population. Exactly how the stellar distributio…
Star Cluster Formation from Turbulent Clumps. III. Across the mass spectrum
Juan P. Farias, Jonathan C. Tan
We study the formation and early evolution of star clusters that have a wide range of masses and background cloud mass surface densities, , which help set the initia…
The SOFIA Massive (SOMA) Star Formation Survey. IV. Isolated Protostars
Ruben Fedriani, Jonathan C. Tan, Zoie Telkamp +13
We present m SOFIA-FORCAST images of 11 isolated protostars as part of the SOFIA Massive (SOMA) Star Formation Survey, with this morphological classification based on…
Are hierarchically formed embedded star clusters surviving gas expulsion depending on their initial conditions?
R. Domínguez, J. P. Farias, M. Fellhauer +1
We investigate the dissolution process of young embedded star clusters with different primordial mass segregation levels using fractal distributions by means of N-body simulations.…
Hunting for Runaways from the Orion Nebula Cluster
Juan P. Farias, Jonathan C. Tan, Laurent Eyer
We use Gaia DR2 to hunt for runaway stars from the Orion Nebula Cluster (ONC). We search a region extending 45° around the ONC and out to 1 kpc to find sources that overlapped in a…
The High-Mass Protostellar Population of a Massive Infrared Dark Cloud
Emily Moser, Mengyao Liu, Jonathan C. Tan +3
We conduct a census of the high-mass protostellar population of the Infrared Dark Cloud (IRDC) G028.37+00.07, identifying 35 sources based on their m e…
Star Cluster Formation from Turbulent Clumps. II. Gradual Star Cluster Formation
Juan P. Farias, Jonathan C. Tan, Sourav Chatterjee
We investigate the dynamical evolution of star clusters during their formation, assuming that they are born from a turbulent starless clump of a given mass that is embedded within…
Gas expulsion in highly substructured embedded star clusters
J. P. Farias, M. Fellhauer, R. Smith +2
We investigate the response of initially substructured, young, embedded star clusters to instantaneous gas expulsion of their natal gas. We introduce primordial substructure to the…
On the Formation of Runaway Stars BN and x in the Orion Nebula Cluster
Juan P. Farias, Jonathan C. Tan
We explore scenarios for the dynamical ejection of stars BN and x from source I in the Kleinmann-Low nebula of the Orion Nebula Cluster (ONC), which is important for being the clos…
How fast is mass-segregation happening in hierarchical formed embedded star clusters?
R. Dominguez, M. Fellhauer, M. Blana +2
We investigate the evolution of mass segregation in initially sub-structured young embedded star clusters with two different background potentials mimicking the gas. Our clusters a…
Star Cluster Formation from Turbulent Clumps. I. The Fast Formation Limit
Juan P. Farias, Jonathan C. Tan, Sourav Chatterjee
We investigate the formation and early evolution of star clusters assuming that they form from a turbulent starless clump of given mass bounded inside a parent self-gravitating mol…
Could Segue 1 be a destroyed star cluster? - a dynamical perspective
Raul Dominguez, Michael Fellhauer, Matias Blaña +5
We attempt to find a progenitor for the ultra-faint object Segue 1 under the assumption that it formed as a dark matter free star cluster in the past. We look for orbits, using the…
The difficult early stages of embedded star clusters and the importance of the pre-gas expulsion virial ratio
J. P. Farias, R. Smith, M. Fellhauer +4
We examine the effects of gas-expulsion on initially substructured distributions of stars. We perform N-body simulations of the evolution of these distributions in a static backgro…
Life and death of a hero - Lessons learned from modeling the dwarf spheroidal Hercules: an incorrect orbit?
M. Blana, M. Fellhauer, R. Smith +3
Hercules is a dwarf spheroidal satellite of the Milky Way, found at a distance of about 138 kpc, and showing evidence of tidal disruption. It is very elongated and exhibits a veloc…
Ursa Major II - Reproducing the observed properties through tidal disruption
R. Smith, M. Fellhauer, G. N. Candlish +3

The impact of galaxy harassment on the globular cluster systems of early-type cluster dwarf galaxies
Rory Smith, Ruben Sanchez-Janssen, Michael Fellhauer +3
The dynamics of globular cluster systems (GCSs) around galaxies are often used to assess the total enclosed mass, and even to constrain the dark matter distribution. The globular c…
