A machine-learning-driven dataset of 144,111 polycyclic aromatic hydrocarbon infrared spectra for interpreting aromatic infrared bands
Xinghong Mai, Zu-Jia Lu, Zhao Wang
The interpretation of interstellar aromatic infrared bands (AIBs) relies on reference spectral libraries, but the chemical space covered by existing databases remains incomplete re…
Beyond Idealized PAHs: Infrared Signatures of Carbon-Chain Defects from Shock Synthesis
Xiaoting Tan, Zhao Wang, Zu-Jia Lu +2
Polycyclic aromatic hydrocarbons (PAHs) are widely recognized as carriers of the aromatic infrared bands (AIBs). However, most spectral models rely on idealized structures that fai…
Tracing expansion-driven star formation in the Perseus molecular cloud using young stellar objects
Chen-Rui Gu, Zhi-Kai Zhu, Zu-Jia Lu +3
. Recent studies have linked star formation in the solar neighbourhood to the expansion of the Local Bubble. The Per-Tau Shell (PTS), a vast 3D dust structure hosting the…
Fragmentation of massive clumps: constant mass fraction and growing mass inequality of cores
Zu-Jia Lu, Qi-Tian Chen
The fragmentation of massive molecular clumps into dense cores sets the initial conditions for stellar clusters, yet how core mass distributions evolve remains unclear. Using the A…
From filaments to clumps: filament properties with synthetic Herschel observations
Zhen-Xing Ma, Zu-Jia Lu
Systematic surveys of filaments have been conducted to study their properties and their relationship to the process of star formation. In this paper, we use synthetic Herschel obse…
B-field Orion Protostellar Survey (BOPS). IV: The Relative Orientation Between Magnetic Fields and Density Structures in Young Protostellar Envelopes
Kexin Cai, Bo Huang, Josep Miquel Girart +7
We investigate the relative alignment between density structures and magnetic fields in eight young protostars from the ALMA B-field Orion Protostellar Survey. Column density maps…
Machine Learning in Stellar Astronomy: Progress up to 2024
Guangping Li, Zujia Lu, Junzhi Wang +1
Machine learning (ML) has become a key tool in astronomy, driving advancements in the analysis and interpretation of complex datasets from observations. This article reviews the ap…
Kinematics of Young Stellar Objects Under Various Stellar Feedback
Longhui Yang, Dejian Liu, Chaojie Hao +6
Based on the Gaia Data Release 3 and APOGEE datasets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-form…
Updated kinematics of the Radcliffe Wave: non-synchronous, dipole-like vertical oscillations
Zhi-Kai Zhu, Min Fang, Zu-Jia Lu +6
The kinematic information of the Radcliffe Wave (RW) is essential for determining its existence and gaining insights into its origin and evolution. In this work, we present an accu…
The Dynamical State of Massive Clumps
Zu-Jia Lu, Veli-Matti Pelkonen, Mika Juvela +3
The dynamical state of massive clumps is key to our understanding of the formation of massive stars. In this work, we study the kinematic properties of massive clumps using synthet…
Physical Properties and Real Nature of Massive Clumps in the Galaxy
Zu-Jia Lu, Veli-Matti Pelkonen, Mika Juvela +3
Systematic surveys of massive clumps have been carried out to study the conditions leading to the formation of massive stars. These clumps are typically at large distances and unre…
The Effect of Supernovae on the Turbulence and Dispersal of Molecular Clouds
Zu-Jia Lu, Veli-Matti Pelkonen, Paolo Padoan +3
While the importance of supernova feedback in galaxies is well established, its role on the scale of molecular clouds is still debated. In this work, we focus on the impact of supe…
Variabilities of Gamma-ray Bursts from Black Hole Hyper-accretion Disks
Da-Bin Lin, Zu-Jia Lu, Hui-Jun Mu +5
The emission from black hole binaries (BHBs) and active galactic nuclei (AGNs) displays significant aperiodic variabilities. The most promising explanation for these variabilities…
On the Late-Time Spectral Softening Found in X-ray Afterglows of Gamma-Ray Bursts
Yuan-Zhu Wang, Yinan Zhao, Lang Shao +2
Strong spectral softening has been revealed in the late X-ray afterglows of some gamma-ray bursts (GRBs). The scenario of X-ray scattering around circum-burst dusty medium has been…
Correlations of Disk and Jet Emission Deviating from the Fundamental Plane
Da-Bin Lin, Wei-Min Gu, Hui-Jun Mu +3
The variability of accretion rate, which is believed to induce the aperiodic variability of X-ray emission from disk, may affect the energy injection into the jet. In this spirit,…
