THE ASTROSPHERE OF THE ASYMPTOTIC GIANT BRANCH STAR IRC+10216 [PDF]

open access: yesThe Astrophysical Journal, 2010
We have discovered a very extended shock structure (i.e., with a diameter of about 24 arcmin) surrounding the well-known carbon star IRC+10216 in ultraviolet images taken with the GALEX satellite. We conclude that this structure results from the interaction of IRC+10216's molecular wind with the interstellar medium (ISM), as it moves through the latter.

On stellar activity cycle-related cosmic ray modulation effects in the astrosphere of Proxima Centauri

open access: yesJournal of Space Weather and Space Climate
In the heliosphere, solar cycle-related changes in galactic cosmic ray (GCR) intensities have long been known to arise as a direct consequence of solar cyclic changes in, for example, the heliospheric magnetic field and the solar tilt angle.

On the Diversity of M-star Astrospheres and the Role of Galactic Cosmic Rays Within [PDF]

open access: yesThe Astrophysical Journal Letters, 2020
Abstract With upcoming missions such as the James Webb Space Telescope, the European Extremely Large Telescope, and the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, we soon will be on the verge of detecting and characterizing Earth-like exoplanetary atmospheres for the first time.

Closing of the astrotail

open access: yes, 2022
Context. The structure of astrospheres depends on the interaction between the host star and the surrounding interstellar medium (ISM). Observations of astrospheres offer new opportunities to learn about the details of this interaction. Aims.

Complementary interstellar detections from the heliotail

open access: yesFrontiers in Astronomy and Space Sciences
The heliosphere is a protective shield around the solar system created by the Sun’s interaction with the local interstellar medium (LISM) through the solar wind, transients, and interplanetary magnetic field.

Evidence of a Thick Heliopause Boundary Layer Resulting from Active Magnetic Reconnection with the Interstellar Medium

open access: yesThe Astrophysical Journal
Voyager 1 and 2 data from the vicinity of the heliopause and very local interstellar medium are reexamined to better understand the confounding lack of rotation in the magnetic field ( B -field) across the heliopause observed by both Voyagers, despite ...

Lyman-alpha observations of astrospheres

open access: yes, 2014
Charge-exchange reactions between outflowing stellar wind protons and interstellar neutral hydrogen atoms entering a stellar astrosphere produce a region of piled-up-decelerated neutral hydrogen called the hydrogen wall. Absorption by this gas, which is observed in stellar Lyman-alpha emission lines, provides the only viable technique at this time for ...
