CO observations of candidates for carbon-rich asymptotic giant branch and post-asymptotic giant branch stars [PDF]
The Astrophysical Journal, 1993 Circumstellar CO emission has been detected in a number of featureless or weak SiC emission, low color temperature IRAS sources. The CO detections confirm the suggestion that these are either extreme carbon stars, carbon-rich proto-planetary nebulae (PPNs), or carbon-rich planetary nebulae (PNs).

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.

New light on Galactic post-asymptotic giant branch stars - I. First distance catalogue [PDF]
, 2014 We have commenced a detailed analysis of the known sample of Galactic post-asymptotic giant branch (PAGB) objects compiled in the Toru´ n catalogue of Szczerba et al., and present, for the first time, homogeneously derived distance determinations for the

Topographic Drag at the Core‐Mantle Interface
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.Abstract The length of day variations with periods from five to one hundred years are mainly due to core‐mantle interactions. Assuming a differential velocity between the core and the mantle, we investigate the pressure coupling on a core‐mantle boundary (CMB) interface with topography. Including rotation, buoyancy, and magnetic effects in local models

Ba Enrichment in Gaia MS+WD Binaries: Tracing s-process Element Production
The Astrophysical Journal LettersA large population of intermediate-separation binaries, consisting of a main-sequence (MS) star and a white dwarf (WD), recently emerged from Gaia’s third data release (DR3), posing challenges to current models of binary evolution. Here we examine the s -

Evolution of thermally pulsing asymptotic giant branch stars - I. The COLIBRI code [PDF]
, 2013 We present the COLIBRI code for computing the evolution of stars along the TP-AGB phase. Compared to purely synthetic TP-AGB codes, COLIBRI relaxes a significant part of their analytic formalism in favour of a detailed physics applied to a complete ...

The origin of the spurious iron spread in the globular cluster NGC 3201
, 2015 NGC 3201 is a globular cluster suspected to have an intrinsic spread in the iron content. We re-analysed a sample of 21 cluster stars observed with UVES-FLAMES at the Very Large Telescope and for which Simmerer et al.
