1. 1. Molecular gas around the binary star R Aquarii

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Terese Olander; [2017]
   Nyckelord :R Aquarii; R Aqr; circumstellar envelope; CSE; CO;

   Sammanfattning : At the end of the lives of low- to intermediate mass stars they can be found on the asymptotic giant branch (AGB). The AGB phase ends when the entire circumstellar envelope (CSE) is blown away in a superwindphase, in the end creating a planetary nebula. It is unknown what shapes the CSE and the planetary nebula. Binarity is a favored theory. LÄS MER

3. 2. The magnetic field of ε Eri

   Kandidat-uppsats, Institutionen för fysik och astronomi

   Författare :Terese Olander; [2013]
   Nyckelord :;

   Sammanfattning : The magnetic eld of the star, ε Eri, is investigated. It is a nearbyK2V star. Previous studies have shown indications of a magnetic eld,but no measurements have been done with polarization. The Zeemaneect causes the lines in the spectrum to be split. LÄS MER
