The Sun is located in a low-density region of the interstellar medium partially filled with hot gas that is the likely result of several nearby supernova explosions within the last 10 Myr. Here we use astrometric data to show that part of the Scorpius-Centaurus OB association was located closer to the present position of the Sun 5-7 Myr ago than today. Evolutionary synthesis models indicate that the association must have experienced ~20 supernova explosions in the last 10-12 Myr, a prediction… 
Star formation near the Sun is driven by expansion of the Local Bubble
TLDR
Three-dimensional analysis of the solar neighbourhood shows that nearly all star-forming regions near the Sun lie on the surface of the Local Bubble, which was inflated by supernovae about 14 million years ago, providing robust observational support for the theory of supernova-driven star formation.
Origin of the Local Bubble
AbstractWe present a new unbiased search for OB associations in the Solar neighbourhood which have hosted the progenitor stars of the core collapse supernovae responsible for the Local Bubble in the
Long term variability of heliopause due to changing conditions in local interstellar medium
Recent studies have shown that local environment of the Sun is a complex one with the presence of several supernova shock bubbles and interstellar clouds in the local interstellar medium (LISM). Even
The Local Bubble and Interstellar Material Near the Sun
Abstract The properties of interstellar matter at the Sun are regulated by our location with respect to a void in the local matter distribution, known as the Local Bubble. The Local Bubble (LB) is
The trouble with the Local Bubble
The model of a Local Hot Bubble has been widely accepted as providing a framework that can explain the ubiquitous presence of the soft X-ray background diffuse emission. We summarize the current
Young Stars Near the Sun
▪ Abstract Until the late 1990s the rich Hyades and the sparse UMa clusters were the only coeval, comoving concentrations of stars known within 60 pc of Earth. Both are hundreds of millions of years
Modeling the magnetized Local Bubble from dust data
The Sun is embedded in the so-called Local Bubble (LB) – a cavity of hot plasma created by supernova explosions and surrounded by a shell of cold, dusty gas. Knowing the local distortion of the
Pressure and Ionization Balances in the Circum-Heliospheric Interstellar Medium and the Local Bubble
A disconcerting mismatch of thermal pressures for two media in contact with each other, (1) the warm, Circum-Heliospheric Interstellar Medium (CHISM) and (2) the very hot material within a much
The search for the origin of the Local Bubble redivivus
ABSTRACT We present anew unbiasedsearchand analysisofall B starsin the solarneighbourhood(within a volume of 400 pc diameter) using the Arivel data base to track down theremains of the OB
Astrophysics in 2002
This has been the Year of the Baryon. Some low temperature ones were seen at high redshift, some high temperature ones were seen at low redshift, and some cooling ones were (probably) reheated.
