Overview of article related to Rotation periods of asteroids

The Yarkovsky effect is a phenomenon that causes force to act on a rotating celestial body, such as an asteroid, due to the way it absorbs and re-emits sunlight as heat. The Yarkovsky effect depends on many physical and surface properties of the body such as diameter, albedo, density, obliquity, and...

Key Points of article about new hydrogen-deficient white star

Scientists found 3 pre-white dwarfs (WDs) with helium-dominated atmospheres.They calculated the effective temperature and surface gravity by comparing the He II line profiles of different stars.Tübingen Model-Atmosphere Package tool was used for spectral analysis and to compute nonlocal thermodynamic...

Overview: Magnetic Field for Jupiter and Neptune Class exoplanets

Dynamo is the process by which a planetary magnetic field is generated through the movement of electrically conductive materials within the planet's interior. The dynamo region is identified based on the magnetic Reynolds number.At the top of this region, the maximum magnetic field is  where...

Key Points of Article about Measuring gravitational waves by graphene

Current detectors can only capture low-frequency gravitational waves.By using graphene, higher frequency gravitational waves can be detected and size of detector also reduced. Here relative intensity varies when gravitational waves are measured.As a gravitational wave propagates through a crystal lattice,...

Summary of Article about Mercury’s plasma environment

The instruments designed to measure ions in Mercury’s plasma environment are: Mass Spectrum Analyzer (MSA), Mass Ion Analyzer (MIA), and Mass Electron Analyzer (MEA).Mass Spectrum Analyzer: This instrument has a spherical top-hat analyzer for energy analysis and a Time-Of-Flight (TOF) chamber for...
