The Massive End of the Stellar Mass Function [PDF]
We derive average flux corrections to the \texttt{Model} magnitudes of the Sloan Digital Sky Survey (SDSS) galaxies by stacking together mosaics of similar galaxies in bins of stellar mass and concentration. Extra flux is detected in the outer low surface brightness part of the galaxies, leading to corrections ranging from 0.05 to 0.32 mag for the ...

Dust input from AGB stars in the Large Magellanic Cloud [PDF]
The dust-forming population of AGB stars and their input to the interstellar dust budget of the Large Magellanic Cloud (LMC) are studied with evolutionary dust models with the main goals (1) to investigate how the amount and composition of dust from AGB ...

The Source of Turbulence in Astrophysical Disks: An Ill-posed Problem. [PDF]
An critical overview of the current state of research in turbulence in astrophysical disks.
arxiv
Helioseismology is one of the most successful fields of astrophysics. The observation and characterization of solar oscillation has allowed solar seismologists to study the internal structure and dynamics of the Sun with unprecedented thoroughness ...

Analysis of stellar spectra with 3D and NLTE models
Models of radiation transport in stellar atmospheres are the hinge of modern astrophysics. Our knowledge of stars, stellar populations, and galaxies is only as good as the theoretical models, which are used for the interpretation of their observed ...

Galactic Archaeology with TESS: Prospects for Testing the Star Formation History in the Solar Neighbourhood [PDF]
A period of quenching between the formation of the thick and thin disks of the Milky Way has been recently proposed to explain the observed age-[{\alpha}/Fe] distribution of stars in the solar neighbourhood.

Archaeology, Epigraphy and Skyscape: Keys to Understanding Dadanite and Lihyanite Conception of Time
ABSTRACT Dadan, the capital of the kingdom of Dadan and, later on, of Lihyan, was an important trading hub and place of worship in North‐West Arabia during the first millennium BCE. Located in the AlUla valley (Saudi Arabia), with naturally available fresh water, fertile soil and relative ease of travel through it, people gathered there for trade ...

Planet Populations as a Function of Stellar Properties
Exoplanets around different types of stars provide a window into the diverse environments in which planets form. This chapter describes the observed relations between exoplanet populations and stellar properties and how they connect to planet formation ...

Review of asteroid, meteor, and meteorite‐type links
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Can star cluster environment affect dust input from massive AGB stars?
We examine the fraction of massive asymptotic giant branch (AGB) stars remaining bound in their parent star clusters and the effect of irradiation of these stars by intracluster ultraviolet (UV) field.
