Pulsating stars in the VMC survey

EPJ Web of Conferences, 2017
The VISTA survey of the Magellanic Clouds system (VMC) began observations in 2009 and since then, it has collected multi-epoch data at Ks and in addition multi-band data in Y and J for a wide range of stellar populations across the Magellanic system ...

The s-Process in Rotating Asymptotic Giant Branch Stars

, 2003
(abridged) We model the nucleosynthesis during the thermal pulse phase of a rotating, solar metallicity AGB star of 3M_sun. Rotationally induced mixing during the thermal pulses produces a layer (~2E-5M_sun) on top of the CO-core where large amounts of ...

Ecological Implications of Germination Temperature on Native and Invasive Rumex Spp.

Plant-Environment Interactions, Volume 6, Issue 2, April 2025.
ABSTRACT Rumex alpinus L. (R. alpinus) is a non‐native invasive plant in Czech mountain regions, altering ecosystem structure and function in protected areas. Rumex obtusifolius L. (R. obtusifolius) is a native species and a problematic weed in Czech meadows, while Rumex longifolius DC. (R.

Theoretical Models for the Late Thermal Pulse in Post-asymptotic Giant Branch Stars: The Case of DY Cen

The Astrophysical Journal
We present theoretical predictions of the born-again scenario for post-asymptotic giant branch stars. An extensive model grid for born-again objects has been constructed, particularly including models for the very late thermal pulse with and without ...

Low-Mass Binary Induced Outflows from Asymptotic Giant Branch Stars [PDF]

, 2006
A significant fraction of planetary nebulae (PNe) and proto-planetary nebulae (PPNe) exhibit aspherical, axisymmetric structures, many of which are highly collimated.

Asymptotic giant branch variables in Baade's Windows [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
In this work, a sample of luminous M-type giants in the Baade's Windows towards the inner Galactic bulge is investigated in the near-infrared. The ISOGAL survey at 7 and 15 μm has given information concerning the mass-loss rates of these stars and their variability characteristics have been extracted from the MACHO data base.

Blueprint for a Universal Theory of Learning to Read: The Combinatorial Model

Reading Research Quarterly, Volume 60, Issue 2, April/May/June 2025.
The Reading Tree. Abstract In this essay, I outline some of the essential ingredients of a universal theory of reading acquisition, one that seeks to highlight commonalities while embracing the global diversity of languages, writing systems, and cultures.
