Mass-luminosity relation of low mass stars
The data on dynamic masses and multicolor photometry of 56 M-type components of binary/multiple systems was collected. Critical evaluation of late type stars bolometric correction scales have been performed. Our refined and reduced data is comparedwith published empirical and theoreticalmassluminosity relations. Our data does not exclude the existence of a step-like feature at MV = 12m. The bes...
متن کاملIntermediate Mass Stars: Updated Models
A new set of stellar models in the mass range 1.2 to 9 M⊙ is presented. The adopted chemical compositions cover the typical galactic values, namely 0.0001 ≤ Z ≤ 0.02 and 0.23 ≤ Y ≤ 0.28. A comparison among the most recent compilations of similar stellar models is also discussed. The main conclusion is that the differencies among the various evolutionary results are still rather large. For examp...
متن کاملNucleosynthesis in Intermediate Mass Stars
We discuss nucleosynthesis within 6 M models with Z = 0:02, 0:008 and 0:004. The emphasis is on the AGB phase of evolution, with particular reference to thermal pulses and Hot Bottom Burning. We nd strong CN cycling, with substantial Al production, especially at low metallicities.
متن کاملNew theoretical yields of intermediate mass stars
We present theoretical yields of H, 16 O for stars with initial masses between 0.8 and 8 M ⊙ and initial metallicities Z = 0.001, 0.004, 0.008, 0.02, and 0.04. We use the evolutionary tracks of the Geneva group up to the early asymptotic giant branch (AGB) in combination with a synthetic thermal-pulsing AGB evolution model to follow in detail the chemical evolution and mass loss up to the end o...
متن کاملMagnetic Properties of Intermediate-mass Stars
Magnetic fields play an important role in producing and modifying the photospheric chemical peculiarities of intermediate-mass main sequence stars. This article discusses the basic theory and methods of measurement used to detect and characterise stellar magnetic fields, and reviews our current knowledge of selected characteristics of magnetic fields in intermediate-mass stars.
