Context: Data from the recently launched astrometric satellite Gaia will be coming in soon with the final data release expected in 2022. This will provide a very precise map of the Galaxy. The Solar system and Galaxy is thought to be filled with invisible bodies (planetesimals, planets, brown dwarfs, neutron stars, black holes, etc.) and they will affect the observations via gravitational lensing.

Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. Large surveys are up and coming, and several surveys are already working, and with these, the aim is high quality abundance measurements of several ele

Purpose: even in the era of exponential increase in the amount of stellar data gathered, binaries are still often overlooked in observational data due to the special handling they require. The goal of this work is to develop a method capable of automatically and efficiently identifying and extract double-lined spectroscopic binaries (SB2) from a spectroscopic survey, while being scalable and techn

Idag vet man att det finns planeter även utanför vårt solsystem, de snurrar runt sina stjärnor precis som vi snurrar runt Solen - vår stjärna. Man kallar dem `exoplaneter', och hittills har man detekterat över tusen stycken. En del av alla dessa exoplaneter har till synes underliga egenskaper: Deras omloppsbanor är väldigt små, endast några hundradelar av Jordens omloppsbana, samtidigt som de The origin of the class of exoplanets typically referred to as hot Jupiters is to this day an unsettled matter. Some of the proposed formation channels predict certain values of the spin-orbit misalignment parameter, i.e. the angle between the stellar rotation axis, and the angular momentum vector of the planet orbit. One such formation channel is tidal capture following Kozai resonance (TCKR). Th

In this summary I briefly discuss some of the many interesting talks presented at this symposium.

Arbetet utreder faderskapspresumtionen och närliggande rättsområden. Syftet med detta är att granska presumtionen och utvärdera om denna är att anse fyll-ler sitt syfte. Detta görs genom att analysera såväl hur det sett ut historiskt som att konstatera hur den gällande rätten ser ut. Detta har även ställts emot de intressen som finns i samhället, hos föräldrarna samt principen om barnets bästa. HThe project audits the presumption of fatherhood in the Swedish legal system and related legal areas. This is done to evaluate if the presumption is fulfilling its purpose. To achieve this a thorough analysis of the subject is conducted. The history of the legal area is explored, and the applicable law is reviewed. The interests in of the different involved parties such as the parents and the publ

Three students about their stay at NanoLund Are you a high school student interested in nanoscience and nanotechnology? Three of our NanoLund summer scholarship holders tell us about their experiences. Hanna Kunatowska, Tycho Braheskolan in Helsingborg“I heard about the summer scholarship at NanoLund through a former scholarship holder who gave a presentation about her experience. After getting an
