The phrase "au and beyond" is not correct in standard written English.
It seems to be a typographical error or a misinterpretation of "and beyond."
Example: "We aim to explore the universe and beyond in our research."
Alternatives: "and further" or "and more."
Close to the nascent Sun, temperatures are too high for water to condense from gaseous form to ice, but, at the distance of present-day Jupiter (approximately 5 AU) and beyond, water ice can form.
The peak solar wind speeds of high-speed streams are typically 750 to 800 km/s at 1 AU and beyond (Tsurutani et al. 1995; Tsurutani and Ho 1999), but here, none of these streams have these magnitudes.
The outputs at 0.08 AU are then used to provide inputs for the lower boundary, at that location, of the 3D MHD code to calculate solar wind and its evolution to 1 AU and beyond.
Short-period comets (those with orbits of up to 200 years) are generally accepted to have emerged from either the Kuiper belt or the scattered disc, which are two linked flat discs of icy debris beyond Neptune's orbit at 30 AU and jointly extending out beyond 100 AU from the Sun.
Voyager 2 observations beyond 40 AU and subsequent modeling suggest that interplanetary shocks may become too weak to continue accelerating energetic particles.
Above and beyond, actually.

Today, we are treating more than 1,000 patients a day at hospitals and clinics in Port-au-Prince and beyond.
As much as I like a good roast chicken, I have always had a soft spot for simmered and boiled chicken, from iconic meaty Mexican soups to down-home American chicken and dumplings, to the French poule-au-pot and beyond.
Figure 3 shows the mean excess function M u) of AU and a linearly decreasing tendency (γ < 0) beyond u of 1500.
Many short-period comets are thought to come from the Kuiper belt, a region lying mainly between 30 AU and 50 AU from the Sun beyond Neptune's orbit but including part of Pluto's and housing perhaps hundreds of millions of comet nuclei.
