We describe the interface between the outer heliosphere and the local interstellar medium (LISM) surrounding the Sun. The components of the inner LISM are the four partially ionized clouds (the Local Interstellar Cloud (LIC), G cloud, Blue cloud, and Aql cloud) that are in contact with the outer heliosphere, and ionized gas produced by EUV radiation primarily from ϵ CMa. We construct the three-dimensional shape of the LIC based on interstellar line absorption along 62 sightlines and show that…

An In Situ Study of Turbulence near Stellar Bow Shocks
Stellar bow shocks are observed in a variety of interstellar environments and shaped by the conditions of gas in the interstellar medium (ISM). In situ measurements of turbulent density fluctuations
Discovery of a young pre-intermediate polar
We present the discovery of a magnetic field on the white dwarf component in the detached post-common envelope binary (PCEB) CC Cet. Magnetic white dwarfs in detached PCEBs are extremely rare, in
Can the Local Bubble explain the radio background?
TheARCADE2 balloon bolometer alongwith a number of other instruments have detectedwhat appears to be a radio synchrotron background at frequencies below about 3 GHz. Neither extragalactic radio
The TeV Cosmic-Ray Bump: A Message from the Epsilon Indi or Epsilon Eridani Star?
It is proposed that Epsilon Indi and Epsilon Eridani can produce the observed spectral bump, and the fit critically requires the I-K spectrum predicted by the model and rules out the alternatives.
In the Trenches of the Solar–Stellar Connection. III. The HST/COS Ecliptic-poles Stellar Survey (EclipSS)
The Ecliptic-poles Stellar Survey (EclipSS) collected far-ultraviolet (FUV: 1160–1420 Å) spectra of 49 nearby (d ≲ 100 pc) F3–K3 main-sequence stars, located at high ecliptic latitudes (north and
Magnetic and Rotational Evolution of ρ CrB from Asteroseismology with TESS
During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent observations suggest that rotation rates
Evidence From Galactic Cosmic Rays That the Sun Has Likely Entered a Secular Minimum in Solar Activity
Since the beginning of the space age, the Sun has been in a multi‐cycle period of elevated activity (secular maximum). This secular maximum is the longest in the last 9300 years. Since the end of
DEUCE: a sounding-rocket ultraviolet spectrograph for flux-calibrated B star observations across the Lyman limit
Abstract. The Dual-channel Extreme Ultraviolet Continuum Experiment (DEUCE) is a rocket-borne, ultraviolet spectrograph specifically designed to obtain the first flux-calibrated spectra of nearby B
NExtUP: the Normal-incidence Extreme Ultraviolet Photometer
The Normal-incidence Extreme Ultraviolet Photometer (NExtUP) is a smallsat mission concept designed to measure the EUV radiation conditions of exoplanet host stars, and F-M type stars in general. EUV


The Interstellar Medium Surrounding the Sun
The Solar System is embedded in a flow of low-density, warm, and partially ionized interstellar material that has been sampled directly by in situ measurements of interstellar neutral gas and dust in
Three recent results related to the heliosphere and the local interstellar medium (ISM) have provided an improved insight into the distribution and conditions of material in the solar neighborhood.
The solar wind emanating from the Sun interacts with the local interstellar medium (LISM), forming the heliosphere. Hydrogen energetic neutral atoms (ENAs) produced by the solar-interstellar
The Properties of the Local Interstellar Medium and the Interaction of the Stellar Winds of epsilon INDI and lambda Andromedae with the Interstellar Environment
We present new observations of the Ly alpha lines of Epsilon Indi (K5 5) and A Andromedae (G8 4-3 + ?) These data were obtained by the Goddard High Resolution Spectrograph (GHRS) on the Hubble Space
The Structure of the Local Interstellar Medium. IV. Dynamics, Morphology, Physical Properties, and Implications of Cloud-Cloud Interactions
We present an empirical dynamical model of the LISM based on 270 radial velocity measurements for 157 sight lines toward nearby stars. Physical parameter measurements (i.e., temperature, turbulent
The interstellar cloud surrounding the Sun: a new perspective
Aims: We offer a new, simpler picture of the local interstellar medium, made of a single continuous cloud enveloping the Sun. This new outlook enables the description of a diffuse cloud from within
The origin of the local 1/4-keV X-ray flux in both charge exchange and a hot bubble
Observations show that the total solar-wind charge-exchange contribution is approximately 40 per cent of the 1/4-keV flux in the Galactic plane, which supports the notion of a million-degree hot bubble extending about a hundred parsecs from the Sun.
Microstructure of the Local Interstellar Cloud and the Identification of the Hyades Cloud
We analyze high-resolution UV spectra of the Mg II h and k lines for 18 members of the Hyades to study inhomogeneity along these proximate lines of sight. The observations were taken by the Space
