Amanda Karakas One of the most important research fields in astrophysics is the study of the origin of the elements. ... Asymptotic Giant Blanch (AGB) Stars: For low and intermediate-mass stars (with initial masses between about 0.8 to 8 solar masses) the most important nucleosynthesis occurs when stars evolve off the main sequence to the giant branches. ... This indicates that these stars obtained their unusual abundances via mass transfer from a previous red giant star, that has long evolved away. ...

... Basics of Group Theory Definition 1. A group G is a (finite or infinite) set of elements g1 , g2 , g3 , . ... Definition 2. ... Each element of a finite group may be represented as a power or product of powers of a certain finite number of elements cal led generators of the group. ... Point Groups Any transformation which brings a body into coincidence with itself can be decomposed into elementary transformations: 1) rotation about an axis, 2) reflection in a plane, 3) translation by some vector. ...

The isotopic fractionation, i.e., the chemical process by which less abundant stable isotopes of elements are transferred to molecules, is still not well-understood. ... The sensitivity of sub-millimeter (ALMA, NOEMA, APEX, IRAM-30m) and IR (Spitzer, Herschel) observational facilities, and new chemical models are starting to shed light also on the fractionation of elements less abundant than H, with special attention to the possible link between this process and the evolution of the host environment. ...

... Content Model: %Body.Content . ... Note that the ID, LANG and CLASS attributes can be used with virtually all of the elements permitted in the document body. ... CLASS . ... The CLASS attribute is most commonly used to attach a different style to some element, but it is recommended that where practical class names should be picked on the basis of the element's semantics, as this will permit other uses, such as restricting search through documents by matching on element class names. ...

The iron abundance in the helium star HD\,144941 has been measured from ultraviolet \ion{Fe}{iii} lines. It is $1.9\pm0.2$ dex below solar and confirms the low metallicity ($Z=0.0003$) previously determined from measurements of CNO and other light elements. The result is important because the low CNO metallicity must be reflected in the iron-group elements in order to explain why HD\,144941 does not show pulsations.
