We report on the interstellar scintillation from pulsar J2048-1616 for the first time at 732, 1369, and 3100 MHz observed with the Parkes 64 m radio telescope. Dynamic spectra are obtained and diffractive parameters are derived from two-dimensional autocorrelation analyses. The frequency dependencies of the observed diffractive scintillation timescale and decorrelation bandwidth indicate that the electron density fluctuations in the interstellar medium (ISM) do not follow the Kolmogorov spectrum. The secondary spectra are calculated by forming the Fourier power spectra of the corresponding dynamic spectra. Prominent parabolic arcs are revealed in the secondary spectra at three frequencies, which indicate that they originated from scattering by a thin screen. The scattering screen is approximately located centrally between the pulsar and Earth assuming that the ISM is stationary. | 9 |

We review recent works on the dynamics of circumbinary accretion, including time variability, angular momentum transfer between the disk and the binary, and the secular evolution of accreting binaries. These dynamics impact stellar binary formation/evolution, circumbinary planet formation/migration, and the evolution of (super)massive black hole binaries. We discuss the dynamics and evolution of inclined/warped circumbinary disks and connect with observations of protoplanetary disks. A special kind of circumbinary accretion involves binaries embedded in big disks, which may contribute to the mergers of stellar-mass black holes in AGN disks. Highlights include the following: <label>■</label>Circumbinary accretion is highly variable, being modulated at P<SUB>b</SUB> (the binary period) or ∼5P<SUB>b</SUB>, depending on the binary eccentricity e<SUB>b</SUB> and mass ratio q<SUB>b</SUB>.<label>■</label>The inner region of the circumbinary disk can develop coherent eccentric structure, which may modulate the accretion and affect the physical processes (e.g., planet migration) taking place in the disk.<label>■</label>Over long timescales, circumbinary accretion steers binaries toward equal masses, and it does not always lead to binary orbital decay. The secular orbital evolution depends on the binary parameters (e<SUB>b</SUB> and q<SUB>b</SUB>) and on the thermodynamic properties of the accreting gas.<label>■</label>A misaligned disk around a low-eccentricity binary tends to evolve toward coplanarity due to viscous dissipation. But when e<SUB>b</SUB> is significant, the disk can evolve toward "polar alignment," with the disk plane perpendicular to the binary plane. | 9 |

Even with several thousand Fermi-Large Area Telescope (LAT) blazar detections, the γ-ray emission mechanism is poorly understood. We explore correlated optical/γ-ray flux variations for 178 Fermi-LAT blazars regularly monitored by the Katzman Automatic Imaging Telescope, the Small and Moderate Aperture Research Telescope System, and the Steward Observatory. Out of the 178 sources, 121 show a measurable (>1σ) discrete correlation function peak. Using the derived time lags and Bayesian block light-curve decompositions, we measure the fraction of common and orphan flares between the two bands. After accounting for sampling and sensitivity limitations we quantify for the first time the true orphan flare rates of optical and γ-ray flares: 54.5% of optical and 20% of γ-ray flares are orphan events. Both the intraband temporal relation and the small orphan γ-ray flare fraction point toward leptonic processes as the likely mechanisms for the high-energy emission. Motivated to discriminate between synchrotron self-Compton (SSC) and external-Compton dominance in individual sources, we use the flux-flux variations to determine the slope m of the log f <SUB>opt</SUB>-log f <SUB> γ </SUB> dependence. The slope distribution suggests a bimodal population with high and intermediate synchrotron peak objects showing larger m than low synchrotron peak objects. We find that m is naturally decreased through pollution from the orphan (typically optical) flares and develop a method to statistically recover, given the sources’ measured orphan flare rate, the intrinsic m. While source classes show composite behavior, the majority of BL Lac objects favor m = 2, indicating an SSC origin for the γ-rays. No preference for either m is found in flat spectrum radio quasars. | 9 |

The solar atmosphere is full of complicated transients manifesting the reconfiguration of the solar magnetic field and plasma. Solar jets represent collimated, beam-like plasma ejections; they are ubiquitous in the solar atmosphere and important for our understanding of solar activities at different scales, the magnetic reconnection process, particle acceleration, coronal heating, solar wind acceleration, as well as other related phenomena. Recent high-spatio-temporal-resolution, wide-temperature coverage and spectroscopic and stereoscopic observations taken by ground-based and space-borne solar telescopes have revealed many valuable new clues to restrict the development of theoretical models. This review aims at providing the reader with the main observational characteristics of solar jets, physical interpretations and models, as well as unsolved outstanding questions in future studies. | 9 |

The most pristine remnants of the Solar System planet formation epoch orbit the Sun beyond Neptune. These are the small bodies of the trans-Neptunian object populations. The bulk of the mass is distributed in ~100 km objects, but objects at smaller sizes have undergone minimum collisional processing. The New Horizons mission recently revealed that the body (486958) Arrokoth, with its effective diameter of ~20 km, appears to be a primordial body and not a collisional fragment. This indicates that bodies at these (and perhaps smaller) sizes retain a record of how they were formed, and they are the most numerous record of this epoch. However, it is impractical to find these bodies with optical surveys because their brightnesses are very low. Their presence can be inferred from the observed cratering record of Pluto and Charon, and it can be directly measured by serendipitous stellar occultations. These two methods produce contradicting results: occultations measure roughly ten times the number of about kilometer-size bodies as are inferred from the cratering record. We used numerical models to explore how these observations can be reconciled with evolutionary models of the outer Solar system. We find that models in which the initial size of the bodies decreases with increasing semimajor axis of formation and models in which the surface density of the bodies increases beyond the 2:1 mean-motion resonance with Neptune can produce both sets of observations, but a comparison to various observational tests favours the former mechanism. We discuss how the astrophysical plausibility of these solutions can be evaluated, and we conclude that extended serendipitous occultation surveys with a broad sky coverage are the most practical approach. | 9 |
