A histidine‐rich extension of the mitochondrial F0 subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria

open access: yesFEBS Letters, EarlyView.
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Destruction of star clusters due to the radial migration in spiral galaxies [PDF]

open access: yes, 2012
Most stars in galactic disks are believed to be born as a member of star clusters or associations. Star clusters formed in disks are disrupted due to the tidal stripping and the evolution of star clusters themselves, and as a results new stars are supplied to the galactic disks.

MODELING JET AND OUTFLOW FEEDBACK DURING STAR CLUSTER FORMATION [PDF]

open access: yes, 2014
Powerful jets and outflows are launched from the protostellar disks around newborn stars. These outflows carry enough mass and momentum to transform the structure of their parent molecular cloud and to potentially control star formation itself.

Calibration of radii and masses of open clusters with a simulation

open access: yes, 2010
Context: A recent new approach to apply a simple dynamical mass estimate of tidally limited star clusters is based on the identification of the tidal radius in a King profile with the dynamical Jacobi radius.

Z-FIRE: ISM properties of the z = 2.095 COSMOS Cluster [PDF]

open access: yes, 2015
We investigate the ISM properties of 13 star-forming galaxies within the z~2 COSMOS cluster. We show that the cluster members have [NII]/Ha and [OIII]/Hb emission-line ratios similar to z~2 field galaxies, yet systematically different emission-line ...

Caloric curve of star clusters [PDF]

open access: yesPhysical Review E, 2012
Self-gravitating systems, like globular clusters or elliptical galaxies, are the prototypes of many-body systems with long-range interactions, and should be the natural arena where to test theoretical predictions on the statistical behaviour of long-range-interacting systems.

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases

open access: yesFEBS Letters, EarlyView.
The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Universal Upper End of the Stellar Initial Mass Function in the Young and Compact LEGUS Clusters

open access: yesThe Astrophysical Journal, 2023
We investigate the variation in the upper end of the stellar initial mass function (uIMF) in 375 young and compact star clusters in five nearby galaxies within ∼5 Mpc. All the young stellar clusters (YSCs) in the sample have ages ≲ 4 Myr and masses above

Star cluster formation in turbulent, magnetized dense clumps with radiative and outflow feedback [PDF]

open access: yes, 2014
We present three Orion simulations of star cluster formation in a 1000 Msun, turbulent molecular cloud clump, including the effects of radiative transfer, protostellar outflows, and magnetic fields.

The Membership and Distance of the Open Cluster Collinder 419

open access: yes, 2010
The young open cluster Collinder 419 surrounds the massive O star, HD 193322, that is itself a remarkable multiple star system containing at least four components.
