Be stars in and around young clusters in the Magellanic Clouds [PDF]

Astronomy and Astrophysics Supplement Series, 1999
We present the results of a search for Be stars in six fields centered on the young clusters NGC 330 and NGC 346 in the SMC, and NGC 1818, NGC 1948, NGC 2004 and NGC 2100 in the LMC. Be stars were identified by differencing R band and narrow-band H$α$ CCD images.

A Tale of Three Dwarfs: No Extreme Cluster Formation in Extreme Star-forming Galaxies

The Astrophysical Journal, 2023
Nearly all current simulations predict that outcomes of the star formation process, such as the fraction of stars that form in bound clusters (Γ), depend on the intensity of star formation activity (Σ _SFR ) in the host galaxy.

Star clusters as building blocks for dSph galaxies formation

, 2009
We study numerically the formation of dSph galaxies. Intense star bursts, e.g. in gas-rich environments, typically produce a few to a few hundred young star clusters, within a region of just a few hundred pc.

The Evolution of Substructure during Star Cluster Assembly

The Astrophysical Journal
Star cluster formation and assembly occur inside filamentary and turbulent molecular clouds, which imprint both spatial and kinematic substructure on the young cluster.

Advanced Camera for Surveys Observations of Young Star Clusters in the Interacting Galaxy UGC 10214

, 2002
We present the first Advanced Camera for Surveys (ACS) observations of young star clusters in the colliding/merging galaxy UGC 10214. The observations were made as part of the Early Release Observation (ERO) program for the newly installed ACS during ...

Star Formation from Galaxies to Globules [PDF]

, 2002
The empirical laws of star formation suggest that galactic-scale gravity is involved, but they do not identify the actual triggering mechanisms for clusters in the final stages.

Variable stars in young open star clusters

Bulletin de la Société Royale des Sciences de Liège, 2018
We have carried out time series photometry of the some young open clusters NGC 1893, Be 59, NGC 7380, Stock 8 and NGC 281 to search for pre-main-sequence variable stars. We have detected several pre-main-sequence variables associated to the young open clusters with periods ranging from ~0.1 to ~50 days.

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

An In-depth Investigation of the Primordial Cluster Pair ASCC 19 and ASCC 21

The Astronomical Journal
Utilizing Gaia data from the literature, we report a new young (∼8.9 Myr) cluster pair, ASCC 19 and ASCC 21, located near the Orion star-forming complex. The clusters are separated by a 3D distance of 27.00 ± 7.51 pc.
