Many types of variable stars obey strict relationships between their pulsation periods and brightnesses. The contributions in this volume offer significant new insights from a wealth of recent observations into the period-luminosity relations governing pulsating variables and their implications for the cosmic distance scale.

Multi-messenger science has a long history in solar astronomy, as direct measures of "in-situ" particles emanating from the Sun, like the solar wind, have long been used alongside remote observations to shape our understanding of the heliosphere. Still, the recent advent of several major observational facilities, such as Parker Solar Probe, Solar Orbiter, and the Inouye Solar Telescope, among many others, is now heralding an exciting new era of scientific opportunities within multi-messenger solar physics. This volume collects the proceedings of IAU Symposium 372 held during the XXXIst IAU General Assembly in Busan, Republic of Korea. Its main goal is to highlight how these facilities can address many of the pressing questions facing contemporary solar physics, with a special emphasis on their coordinated operation and the resulting synergies. Graduate students and researchers in solar physics will benefit from the many new results presented within.

Winds form an integral part of astronomy ¿ from regulating rotation of stars through enriching galaxies with fresh materials. Outflowing winds persist during the entire lives of stars and play a key role in shaping the exoplanet demographics we observe. In massive stars, their winds are a vital ingredient of their evolution, from the main sequence to the pre-supernova stage, determining black hole masses as measured from gravitational waves. In the case of low-mass stars, their winds dictate rotational evolution, which affect angular momentum distribution within the stellar interior and thus the generation of magnetic fields. In the case of planets, winds take the form of atmospheric escape, which can strongly affect their atmospheric evolution. IAU Symposium 370 brings together researchers on winds of exoplanets and stars, including the solar wind, to share insights into the physics and modelling tools used by these different communities.

Blazars, the most extreme active galactic nuclei with powerful relativistic jets extending out to kiloparsecs from their central engine, are among the most intriguing and consistently bright objects in the observable Universe. Understanding how they form and shine has been a cumbersome endeavor since their discovery in the 1960s, with several fundamental questions remaining open to this day. The 2020s mark the beginning of a new era of large-scale surveys, multimessenger astrophysics, high-energy polarization, and extreme angular resolution, setting the ideal stage to study astrophysical jets. IAU Symposium 375 was the first IAU symposium to take place in Nepal. It brought together experts from all aspects of the blazar community to facilitate the building of new collaborative efforts to take advantage of the wealth of incoming data that will help provide answers to long-standing questions. It also supported local efforts to promote astrophysics and astrophysical research in Nepal.

The prime parameter determining the evolution of a star is its mass. Any modification to the stellar mass has large repercussions on its evolutionary path. Both low-mass and massive stars are known to power strong stellar winds at the end of their lives. These winds determine the type of the stellar end product and the amount by which these stars contribute to the chemical enrichment of the interstellar medium, ultimately providing the building blocks of planets and life. A proper understanding of stellar evolution and the building blocks in the Universe cannot be achieved without a detailed understanding of stellar winds. IAU Symposium 366 provides an overview of state-of-the-art observational and theoretical studies on the origin of winds in low-mass and massive evolved stars, with topics including binarity, enrichment of the interstellar medium, astrochemistry, and theoretical, observational and numerical constraints on stellar outflows.

Reviews how feedback processes associated with quasars control the evolution of supermassive black holes and their host galaxies.

The range of phenomena that manifest at all different time and length scales and the wide range of sizes of space objects, from minor bodies in the Solar System to exoplanets, and from dust particles to Jupiter-size bodies, require the development of dynamical modeling and analysis tools that can handle these different scales. This volume collects contributions given by distinguished scientists at the hybrid IAU Symposium 364. The methods in dynamics modeling of space objects have already reached a state of maturity, and their implementation provided a large number of important results pertaining to both the theory and their applications. The contributions cover the recent advances in the multi-scale dynamics of natural and artificial space objects from various perspectives, which will benefit graduate students and researchers working in the fields of celestial mechanics, astrodynamics, planetary sciences, applied mathematics and dynamical systems.

Studies of the perception and transduction of hormonal signals in higher plants are relatively recent. Despite the rather small number of researchers involved in comparison, say, to those studying signalling in animals, plant scientists are becoming attracted to this important field because of the fascinating mechanisms being revealed and the recognition that any hope of understanding the ways in which the growth and development of the whole plant are controlled can only be based on an exploration of the physiology, biochemistry and molecular biology of these mechanisms. The Moscow symposium that gave rise to the present book drew many of the most active workers in the area, and many new developments were revealed. Audience: Important reading for all those interested in plant growth and development.
