The nature and origin of disky elliptical galaxies [PDF]

, 2002
The observational trend that disky elliptical galaxies exhibit younger luminosity- weighted ages than boxy ellipticals is investigated. The presence of a possible young stellar disk embedded in these galaxies is explored by comparing kinematics derived ...

Final report on the STELLAR Delphi study: Future directions for TEL and TEL research: areas of tension, core research areas and grand challenge problems

, 2012
In this report on the STELLAR Delphi study, we present the results of the final global survey, that is the 4th STELLAR Delphi round, and illustrate the elaboration and dissemination of these results (5th STELLAR Delphi round).

Resonant structures in exozodiacal clouds created by exo-Earths in the habitable zone of late-type stars

Astronomy & Astrophysics
Context. Earth-like exoplanets can create resonant structures in exozodiacal dust through mean motion resonances. These structures not only suggest the presence of such planets but also act as potential noise sources in future mid-infrared nulling ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Intermediate report on the Delphi study: Findings from the 2nd and the 3rd STELLAR Delphi rounds: Areas of tension and core research areas

, 2011
This intermediate report on the STELLAR Delphi study closes the gap between the first deliverable on the Delphi study D1.3 (Spada et al. 2010) which was published in July 2010 and the second and final deliverable D1.6 which is planned for January 2012 ...

Axially Symmetric Post-Newtonian Stellar Systems

Revista Integración, 2010
We introduce a method to obtain self-consistent, axially symmetric disklike stellar models in the first post-Newtonian (1PN) approximation. By using in the field equations of the 1PN approximation a distribution function (DF) corresponding to a ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Internal rotation of red giants by asteroseismology

EPJ Web of Conferences, 2013
We present an asteroseismic approach to study the dynamics of the stellar interior in red giant stars by asteroseismic inversion of the splittings induced by the stellar rotation on the oscillation frequencies.

Stellar Collisions in the Galactic Center: Massive Stars, Collision Remnants, and Missing Red Giants

The Astrophysical Journal, 2023
Like most galaxies, the Milky Way harbors a supermassive black hole (SMBH) at its center, surrounded by a nuclear star cluster. In this dense star cluster, direct collisions can occur between stars before they evolve off the main sequence.
