  • Gravitational atmospheric tides as a probe of Titan's Interior: Application to Dragonfly
    2021
    Co-Authors: Charnay Benjamin, Tobie Gabriel, Lebonnois Sébastien, Lorenz, Ralph D.
    Abstract:

    Context: Saturn's massive gravity is expected to causes a tide in Titan's atmosphere, producing a surface pressure variation through the orbit of Titan and tidal winds in the troposphere. The future Dragonfly mission could analyse this exotic meteorological phenomenon. Aims: We analyse the effect of Saturn's tides on Titan's atmosphere and Interior to determine how pressure measurements by Dragonfly could constrain Titan's Interior. Methods: We model atmospheric tides with analytical calculations and with a 3D Global Climate Model (the IPSL-Titan GCM), including the tidal response of the Interior. Results: We predict that the Love numbers of Titan's Interior should verify 1 + Re(k2 - h2) ~ 0.02-0.1 and Im(k2 - h2) < 0.04. The deformation of Titan's Interior should therefore strongly weaken gravitational atmospheric tides, yielding a residual surface pressure amplitude of only ~ 5 Pa, with a phase shift of 5-20 hours. Tidal winds are very weak, of the order of 3*10^-4 m/s in the lower troposphere. Finally, constraints from Dragonfly data may permit the real and the imaginary parts of k2 - h2 to be estimated with a precision of ~0.01-0.03. Conclusions: Measurements of pressure variations by Dragonfly over the whole mission could give valuable constraints on the thickness of Titan's ice shell, and via geophysical models, its heat flux and the density of Titan's internal ocean.Comment: Accepted for publication in A&A. 10 pages, 8 figures, 1 tabl

We model atmospheric tides with analytical calculations and with a 3D Global Climate Model (the IPSL-Titan GCM), including the tidal response of the Interior. Results. We predict that the Love numbers of Titan's Interior should verify 1 + (k 2 − h 2) ∼ 0.02-0.1 and (k 2 − h 2) < 0.04. The deformation of Titan's Interior should therefore strongly weaken gravitational atmospheric tides, yielding a residual surface pressure amplitude of only ∼ 5 Pa, with a phase shift of 5-20 hours. Tidal winds are very weak, of the order of 3×10 −4 m s −1 in the lower troposphere. Finally, constraints from Dragonfly data may permit the real and the imaginary parts of k 2 − h 2 to be estimated with a precision of ±0.01-0.03. Conclusions. Measurements of pressure variations by Dragonfly over the whole mission could give valuable constraints on the thickness of Titan's ice shell, and via geophysical models, its heat flux and the density of Titan's internal ocean

    Co-Authors: Jakimovska Popovska Violeta, Iliev Borche, Spiroski Ivo
    Abstract:

    BACKGROUND: The paper analyzes the properties of medium density fiberboards (MDF) intended for furniture production and Interior Application. Because MDF panels are one of the mostly used wood-based panels in furniture production sector in the Republic of Macedonia it is important to know and understand their basic physical and mechanical properties. AIM: For better understanding of MDF panels and their proper end use by the furniture constructors and designers, physical and mechanical properties of MDF panels present in the market are tested.MATERIALS AND METHODS: Commercially produced MDF panels taken from one company from wood-based panel market were tested. Evaluation of the quality of the panels was made on the basis of the obtained results for the physical and mechanical properties of the panels. Properties of MDF were tested according to the national MKS standards and European norms.RESULTS: Tested MDF panels present on our market are characterized by good physical and mechanical properties that meet the requirements of the standards for MDF for use in dry conditions including furniture production and Interior Applications.CONCLUSIONS: It is recommended to avoid Application of these MDF panels in high humidity conditions for a longer exploitation period. For this kind of Applications, such as bathroom areas, the furniture constructors and Interior designers should consider use of MDF.H type of panel for Application in high humidity conditions, which will provide good dimensional stability of the products during whole exploitation period
