PROJECT-J: the shocking H2 outflow from HH46

Maria Gabriela Navarro, Brunella Nisini, Teresa Giannini +14

We analyze the H2 emission observed in the HH46 Class I system as part of PROJECT-J (Protostellar Jets Cradle Tested with JWST), to investigate the origin and excitation of the war…

A Search for Eclipse Cycles Similar to the Hypersaros: Columbus and the Lunar Eclipse of March 14, 2025

Patrick Hartigan

The total lunar eclipse on March 14, 2025 UT occurs nearly exactly 521 years (one Hypersaros) after a similar eclipse on March 1, 1504 UT that is renowned for its importance to the…

PROJECT-J: JWST observations of HH46~IRS and its outflow. Overview and first results

B. Nisini, M. G. Navarro, T. Giannini +23

We present the first results of the JWST program PROJECT-J (PROtostellar JEts Cradle Tested with JWST ), designed to study the Class I source HH46 IRS and its outflow through NIRSp…

PDRs4All VIII: Mid-IR emission line inventory of the Orion Bar

Dries Van De Putte, Raphael Meshaka, Boris Trahin +135

Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…

A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk

Olivier Berné, Emilie Habart, Els Peeters +143

Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…

High-quality Extragalactic Legacy-field Monitoring (HELM) with DECam

Ming-Yang Zhuang, Qian Yang, Yue Shen +45

High-quality Extragalactic Legacy-field Monitoring (HELM) is a long-term observing program that photometrically monitors several well-studied extragalactic legacy fields with the D…

PDRs4All VI: Probing the Photochemical Evolution of PAHs in the Orion Bar Using Machine Learning Techniques

S. Pasquini, E. Peeters, B. Schefter +21

[Abridged] JWST observations of the Orion Bar have shown the incredible richness of PAH bands and their variation on small scales. We aim to probe the photochemical evolution of PA…

PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula

Emilie Habart, Els Peeters, Olivier Berné +139

The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…

Proper Motions and Shock Wave Dynamics in the HH 7-11 Stellar Jet

P. Hartigan, R. Holcomb, A. Frank

We have used the Hubble Space Telescope to acquire new broad-band and narrow-band images of the optical line emission and red continuum associated with the HH 7-11 stellar jet in t…

On Sunspot and Starspot Lifetimes

Stephen J. Bradshaw, Patrick Hartigan

We consider the lifetimes of spots on the Sun and other stars from the standpoint of magnetic diffusion. While normal magnetic diffusivity predicts lifetimes of sunspots that are t…

Irradiated Interfaces in the Ara OB1, Carina, Eagle Nebula, and Cyg OB2 Massive Star Formation Regions

P. Hartigan, J. Palmer, L. I. Cleeves

Regions of massive star formation offer some of the best and most easily-observed examples of radiation hydrodynamics. Boundaries where fully-ionized H II regions transition to neu…

A Spectroscopic Survey of Subarcsecond Binaries in the Taurus-Auriga Dark Cloud with the Hubble Space Telescope

Patrick Hartigan, Scott Kenyon

We report the results of a spectroscopic survey of 20 close T Tauri binaries in the Taurus-Auriga dark cloud where the separations between primaries and their secondaries are less…
