Here we use synthetic data to explore the performance of forward models and inverse methods for helioseismic holography. Specifically, this work presents the first comprehensive test of inverse modeling for flows using lateral-vantage (deep...
NICER and Fermi GBM Observations of the First Galactic Ultraluminous X-ray Pulsar Swift J0243.6+6124 [0.03%]

Swift J0243.6+6124 is a newly discovered Galactic Be/X-ray binary, revealed in late September 2017 in a giant outburst with a peak luminosity of 2 × 1039(d/7 kpc)2 erg s-1 (0.1-10 keV), with no formerly reported activity. At this luminosit...
ICE CHEMISTRY ON OUTER SOLAR SYSTEM BODIES: ELECTRON RADIOLYSIS OF N2-, CH4-, AND CO-CONTAINING ICES [0.03%]
太阳系外层天体上的冰化学：N2、CH4和CO-containing冰的电子辐射分解

Christopher K Materese et al.
Radiation processing of the surface ices of outer Solar System bodies may be an important process for the production of complex chemical species. The refractory materials resulting from radiation processing of known ices are thought to impa...
Understanding Heating in Active Region Cores through Machine Learning. I. Numerical Modeling and Predicted Observables [0.03%]
基于机器学习的活动区核心加热研究 I. 数值模拟和可观测预言

To adequately constrain the frequency of energy deposition in active region cores in the solar corona, systematic comparisons between detailed models and observational data are needed. In this paper, we describe a pipeline for forward model...
Analysis of the Herschel/HEXOS Spectral Survey Towards Orion South: A massive protostellar envelope with strong external irradiation [0.03%]
赫歇尔/HEXOS光谱巡天或ion南区的分析：强外部辐照的/star包层的分析

K Tahani et al.
We present results from a comprehensive submillimeter spectral survey toward the source Orion South, based on data obtained with the HIFI instrument aboard the Herschel Space Observatory, covering the frequency range 480 to 1900 GHz. We det...

The first computational model of solid-phase chemistry in cometary nuclear ices is presented. An astrochemical kinetics model, MAGICKAL, is adapted to trace the chemical evolution in multiple layers of cometary ice, over a representative pe...
A COMPARISON OF SIMULATED JWST OBSERVATIONS DERIVED FROM EQUILIBRIUM AND NON-EQUILIBRIUM CHEMISTRY MODELS OF GIANT EXOPLANETS [0.03%]
基于巨系外行星平衡和非平衡化学模型的模拟詹姆斯·韦伯空间望远镜观测对比研究
Sarah D Blumenthal,Avi M Mandell,Eric Hébrard et al.
Sarah D Blumenthal et al.
We aim to see if the difference between equilibrium and disequilibrium chemistry is observable in the atmospheres of transiting planets by the James Webb Space Telescope (JWST). We perform a case study comparing the dayside emission spectra...
A Kinematically Cold Structure of Candidate Young OB Stars toward the Anticenter [0.03%]

We combine Galaxy Evolution Explorer and Gaia DR2 catalogs to track star formation in the outskirts of our Galaxy. Using photometry, proper motions, and parallaxes we identify a structure of ~300 OB-type candidates located between 12 and 15...

We calculate the electromagnetic signal of a gamma-ray flare coming from the surface of a neutron star shortly before merger with a black hole companion. Using a new version of the Monte Carlo radiation transport code Pandurata that incorpo...
Young Accreting Compact Objects in M31: The Combined Power of NuSTAR, Chandra, and Hubble [0.03%]
NUSTAR、钱德拉和哈勃的空间观测在M31中发现年轻的密近天体对象

M Lazzarini et al.
We present 15 high-mass X-ray binary (HMXB) candidates in the disk of M31 for which we are able to infer compact object type, spectral type of the donor star, and age using multiwavelength observations from NuSTAR, Chandra, and the Hubble S...
