  1. 1. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering

    Master-uppsats, Linköpings universitet/Plasma och ytbeläggningsfysik

    Författare :Henrik Eliasson; [2021]
    Nyckelord :;

    Sammanfattning : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. LÄS MER

  3. 2. Stars Eating Planets

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :John Wimarsson; [2020]
    Nyckelord :Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

    Sammanfattning : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. LÄS MER

  4. 3. Study of the in-flight calibration of theSVOM/ECLAIRs instrument

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Jakob Östberg; [2020]
    Nyckelord :Telescope; calibration; gamma-ray; burst; ECLAIRs; SVOM; IRAP;

    Sammanfattning : The Space based multi-band Variable astronomical Object Monitor (SVOM) is a x- andgamma-ray telescope with the primary objective of observing gamma-ray bursts. Themission is a cooperation between the French and Chinese space agencies and will be launchedin 2021. LÄS MER

  5. 4. Exploring Absorption in the Host Galaxies of Gamma-Ray Bursts

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Teodor Jonsson; Oscar Wistemar; [2020]
    Nyckelord :;

    Sammanfattning : Gamma-ray bursts (GRB) are extremely high energy pulses that are connected to supernovae and black hole formation. They are divided into two forms, long and short GRBs. LÄS MER

  7. 5. Simulation of Scientific VHF Telemetry Data for the French Payload of the SVOM Satellite

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Florian Reiner; [2019]
    Nyckelord :;

    Sammanfattning : The Space Variable Objects Monitor (SVOM) is a future French-Chinese satellite mission which is dedicated to the observation and characterisation of Gamma Ray Bursts (GRBs). When a GRB is detected by the satellite, the position and initial characterisation data are transmitted to ground via a VHF telemetry link, in order to trigger immediate follow-up observations of the transient GRB afterglow by ground-based telescopes.
