A study of cosmic dust in the galactic environment
… loss rates of these 21 micron sources from their dust infrared (IR) emission, using the "2-DUST" radiative transfer code for axisymmetric dusty systems and examine the correlation between mass loss rate of AGB phase or mass loss rate of superwind phase with that of fluxes emitted from 21 and 30 …

The Well-Dressed Spacecraft: Textiles for Cosmic Dust Metrology
I envision cosmic grains that may have traveled light years to meet, in a microscopic blitz, the commonplace textile! This work brings the first electronic textiles to Low Earth Orbit, tracking advanced fabric sensor characterization from a tabletop laser accelerator, to a warehouse-scale …

Laboratory Studies of Gas-Grain Processes on Cosmic Dust Analogues
… place both in the gas phase and on surfaces of cosmic dust grains. Gas phase reactions alone are found to be insufficient to account for the observed abundance of molecules such as molecular hydrogen, water, carbon dioxide, methanol as well as many other complex molecules; grain surfaces must be …

Trajectory Sensor and Readout Electronics of a Cosmic Dust Telescope
… signals from a trajectory sensor for cosmic dust. The detector is assembled of multiple wire electrodes which allow the determination of direction, speed and charge of cosmic dust. The circuit consists of two units, a low noise charge sensitive amplifier optimized for a specified …

Charging of aggregate grains in astrophysical environments.
… gas in which a portion of particles are ionized. Dust is a ubiquitous component of the universe, and when present in plasma, can form dusty plasma system. Dust in the plasma is generally charged due to the constant collisions with free moving electrons and ions. Cosmic dust can also be charged by …

SPECTROSCOPIC STUDY OF ICES WITH ASTROPHYSICAL INTEREST
… the physical and chemical processes of simulated cosmic dust grainsand planetary surface analogues in laboratory experiments performed at the Syracuse University Astrophysics and Surface Science Laboratory. I have studied the mid-infrared (Mid-IR) bands of thin films of pure CH4 ices and of CH4 …

Circumplanetary dust dynamics : application to Martian dust tori and Enceladus dust plumes
Our Solar system contains a large amount of dust, containing valuable information about our close cosmic environment. If created in a planet's system, the particles stay predominantly in its vicinity and can form extended dust envelopes, tori or rings around them. A fascinating example of these …
