This year's GRS will explore topics ranging from exoplanet detection and characterization, laboratory experiments relevant to planetary formation, advances in astrochemistry and astrobiology, protoplanetary disk observations, numerical simulations of the physical and chemical processes of early solar system formation, insights provided by spacecraft missions to ancient planetary bodies, and more.

Constraining the Origin and Evolution of Planetary Systems Through a Multidisciplinary Approach

The Origins of Solar Systems GRC is a premier, international scientific conference focused on advancing the frontiers of science through the presentation of cutting-edge and unpublished research, prioritizing time for discussion after each talk and fostering informal interactions among scientists of all career stages. In 2023, we will highlight results from recent and ongoing missions including Hyabusa 2, OSIRIS-REx, and JWST, in addition to exciting work from ALMA, other facilities, and from theoretical investigations.

One of the central features of the AAS Summer and Winter Meetings is their plenary talks spanning the full breadth of astrophysics. Some plenaries are given by prize winners from the AAS and other organizations, while other speakers are selected by the AAS Vice Presidents. Most plenary talks present science content, but talks on the state of the profession, demographics, and societal issues of relevance to the astronomical community are also regularly scheduled.

While it is widely acknowledged that string theory provides a framework for addressing quantum gravitational (and even quantum field theoretic) questions, the precise nature of its organizational principle remains obscure. Nearly three decades ago, when the question “What is string theory?” was asked, the perturbative string worldsheet viewpoint played the starring role. Since then, the discovery of D-branes, string dualities, and the holographic AdS/CFT correspondence has had spacetime dynamics taking center-stage. Much insight has been gleaned from these developments. We now have, for example, a much broader class of string backgrounds with better control over compactifications; strong constraints on the low energy effective field theories; a plethora of gauge-string dualities as well as applications of holographic techniques to a wide class of physical problems; and new angles on semiclassical gravitational physics from a fruitful interplay with quantum information in holography. Together with an influx of new tools and techniques, we have a very rich set of perspectives that illuminate the subject we continue to call string theory. While all these developments are interesting in and of themselves, it is an opportune moment to attempt to synthesize these, often disparate, strands and arrive at a deeper answer to the question in the title.

Turbulence is an important process in various astrophysical environments and over vast scales. These environments range from the interior of stars, the solar wind, accretion flows, disks, jets, the interstellar medium and the circumgalactic medium, to the intra-cluster medium. The past few decades have seen great advances in both observational and theoretical studies of astrophysical turbulence. The advances in understanding and measuring turbulence have also brought significant changes to many branches of astronomy.

This conference will bring together turbulence experts from a wide range of subfields in astrophysics and physics. The goal is to encourage and enhance interdisciplinary discussions and collaborations. The conference will cover many topics, including: turbulent dynamo, magnetic reconnection, plasma physics, space physics, unresolved physics and sub-grid models in numerical simulations, turbulence in the laboratory, new observational techniques for diagnosing turbulence, connecting observations and models, and astrophysical applications of magnetized turbulence (e.g. star formation, cosmic rays, accretion, galaxy formation and evolution).

On April 8, 2024, a total solar eclipse will take place in the US, and Waco is very close to the center of the path of totality. This event is a once-in-a-lifetime opportunity to promote science in fields related to astrophysics. With its easy accessibility and historically excellent weather in April, we are delighted to announce the 2024 Waco Eclipse International Astrophysics Conference to be held April 4-8, 2024, at Baylor University, Waco, Texas, USA.

The conference will consist of a three-day (April 5-7) scientific meeting and one day devoted to public outreach and observation of the eclipse (April 8). The conference will address topics such as observations of the solar eclipse, understanding of solar physics and the Sun as a probe to stellar astrophysics and related topics, such as space plasma, planetary systems, dark matter, dark energy, extra-galactic surveys, and the universe.

TESS welcomes participation by the entire Heliophysics community, including all four traditional sub-disciplines devoted to studies of the Sun, Heliosphere, Magnetosphere, and Ionosphere-Thermosphere-Mesosphere.

The Triennial Earth-Sun Summit is a joint meeting of the AAS Solar Physics Division and the Space Physics and Aeronomy Section of the American Geophysical Union.

Tidal disruption events (TDEs), which occur when a star is destroyed by the immense tidal field of a supermassive black hole, fuel luminous accretion flares that provide unique insight into the properties of galactic nuclei and their central black holes. The detection rate of these events has accelerated in recent years thanks to advances in wide-field survey capabilities across the electromagnetic spectrum. Nonetheless, there remain theoretical uncertainties in the modeling of TDEs that obfuscate understanding in the face of observations, and our ability to use TDEs as a collective Rosetta Stone for deciphering black hole demographics across cosmic time remains elusive. To bridge theory and observation and to start to tap the wealth of understanding contained within TDE observations, this conference aims to unite the diverse field of astronomers working on TDEs and the related fields of variable Active Galactic Nuclei (AGN) and X-ray binaries. This conference will highlight the recent advances that have been made in understanding TDEs, make connections to related astrophysical phenomena, and elucidate the most outstanding questions in TDE theory and observation.

The international conference Loops ‘24 is the most recent in a long tradition of biennial meetings focused on loop quantum gravity and background independent approaches to quantum gravity. The conference will be held from Monday, May 6 through Friday, May 10, 2024, at the campus of Florida Atlantic University in Fort Lauderdale, Florida (USA). The program will feature morning plenary talks complemented by contributed talks. Plenary sessions will be held in the auditorium of the Broward County Main Library one block away from the campus. The conference will highlight recent developments in canonical loop quantum gravity, covariant loop quantum gravity (spin foams), and other approaches to quantum gravity, as well as applications to symmetry-reduced models, quantum cosmology, black holes in quantum gravity, and other topics. Foundational, mathematical, numerical and phenomenological aspects will be covered.

Observables spanning a wide range of cosmic epochs and length-scales independently testify to the existence of dark matter. Although little is known about the microphysical nature of dark matter, its mere existence points to physics beyond the Standard Model. New developments in theory, cosmological simulations, and observational capabilities in the era of large surveys have opened up a vast landscape for dark matter discovery, which includes models that can only be tested by astrophysical and cosmological probes.
