Technology requirements of exploration beyond Neptune by solar sail propulsion [PDF]

, 2010
This paper provides a set of requirements for the technology development of a solar sail propelled Interstellar Heliopause Probe mission. The mission is placed in the context of other outer solar systems missions, ranging from a Kuiper Belt mission ...

Turbulence in the interstellar medium [PDF]

, 2014
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

Relative In-flight Response of IBEX-Lo to Interstellar Neutral Helium Atoms

The Astrophysical Journal Supplement Series, 2023
The IBEX-Lo instrument on the Interstellar Boundary Explorer (IBEX) mission measures interstellar neutral (ISN) helium atoms. The detection of helium atoms is made through negative hydrogen (H ^− ) ions sputtered by helium atoms from the IBEX-Lo’s ...

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations [PDF]

, 2001
We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Asymmetric mass-loss from the white dwarf WD 0253+209 : Secret revealed

Bibechana, 2012
Dust structures around the white dwarf WD 0253+209 is studied in 100 and 60 micron infrared image. These images are received from Infrared Astronomical Satellite Survey (IRAS Survey).

Filtration of Interstellar Neutral Helium by Elastic and Charge Exchange Collisions in Heliospheric Boundaries

The Astrophysical Journal, 2023
Interstellar neutral (ISN) helium atoms penetrating the heliosphere are used to find the flow velocity and temperature of the very local interstellar medium near the heliosphere.

Transport of Solar Wind Fluctuations: A Two-Component Model [PDF]

, 2011
We present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.

Are the Heliosphere, Very Local Interstellar Medium, and Local Cavity in Pressure Balance with Galactic Gravity?

The Astrophysical Journal, 2023
The Voyager spacecraft are providing the first in situ measurements of physical properties in the outer heliosphere beyond the heliopause. These data, together with data from the IBEX and Hubble Space Telescope and physical models consistent with these ...

A two-component transport model for solar wind fluctuations: Waves plus quasi-2D turbulence [PDF]

, 2010
We present a model for the transport of solar wind fluctuations, based on the assumption that they can be well-represented using two distinct components: a quasi-2D turbulence piece and a wave-like piece.

Dynamical age of solar wind turbulence in the outer heliosphere [PDF]

, 1998
In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.
