From local chemistry to galactic evolution: unlocking the power of interstellar isotopes with ALMA2040
Molecular isotopic ratios provide a unique window into the chemical evolution of the interstellar medium, linking stellar nucleosynthesis and Galactic chemical evolution to the physical and chemical…Intermediate- and high-resolution optical spectroscopy on the nascent planetary nebula Vy 2-2: Evidence of binary-star evolution
Planetary nebulae (PNe) tend to show spectacular non-spherical shapes whose origin is not fully understood.Multi-wavelength Polarization as a Probe of Planet Formation
Polarization reveals details of circumstellar disks that are not readily available from total intensity observations.A Sample of Thick-Disk Stars Hosting Hot Jupiters
We present a homogeneous analysis of 268 confirmed and candidate transiting hot-Jupiter host stars with 4800K < Teff < 6200K.Chemical Demographics of Star-forming Regions
Our understanding of complex organic chemistry during the formation of stars and planets is shaped by a handful of cherry-picked sources with bright molecular emission lines.The environments forming stellar and planetary systems
How does a star's birth environment set the mass, angular momentum and chemical complexity delivered to its planet-forming disk, and thereby whether it builds planets, brown dwarfs or stellar…Contrasting geometries of kiloparsec-scale stellar flows associated with giant Galactic cavities
Giant bubbles and cavities are widespread in star-forming galactic discs, yet the stellar dynamics associated with such structures remain poorly constrained.Let Sleeping Stars Li: Mapping Turnoff Lithium, the Lithium Dip, & Testing Standard Model Predictions in GALAH DR4 Subgiants
Lithium is an excellent tracer of stellar mixing.Searching for Dwarf Novae in 47 Tucanae
The globular cluster 47 Tucanae has 43 strong cataclysmic variable candidates, four of which are confirmed dwarf novae.Double Trouble: How Unresolved Spectroscopic Binary Stars Skew GALAH DR4 Stellar Parameters
Unresolved binary stars introduce systematic biases in stellar parameter estimates when analysed assuming a single star.Nova shells in 3D: I. A catalog of integral field spectroscopic observations
Classical novae eject material during thermonuclear eruptions on accreting white dwarfs, forming expanding shells whose structures and kinematics provide insights into the eruption mechanism and…A Parsec-scale Circumstellar Shell Around VX Sgr: Mass Loss and RSG/TŻO Nature
A thin, arc-shaped shell is discovered surrounding VX Sagittarii (VX Sgr), the largest known CSM shell around an RSG at a scale $r\sim0.59\,\mathrm{pc}$.JWST Observations of RR Lyrae in Leo P
We analyze co-spatial HST/ACS and JWST/NIRCam time-series photometric observations of RR Lyrae in the low-metallicity dwarf galaxy Leo P. This study provides a new opportunity to explore the…A Search for Dust in the Outflow of the HH212 Class 0 Protostellar System
Perhaps the most visually striking phenomenon during star formation is the ejection of material along the direction of the protostar's rotational axis.Non-equilibrium chemistry and radiation hydrodynamics in metal-poor and metal-rich interstellar gas
We present a flexible implementation of non-equilibrium chemical networks with the $\texttt{KROME}$ framework, coupled to a nonlocal variable Eddington tensor-closed radiation transport scheme…IC 1297: The Most Distant Known X-ray Planetary Nebula and One of the Most Luminous
We present the first targeted Einstein Probe (EP) X-ray observations of any planetary nebula (PN).Dynamical formation of dormant black holes: Predictions for Gaia DR4
Dormant black holes (dormant BHs, i.e., X-ray quiet binaries comprising a BH and a companion star) are probes of the effect of cluster dynamics and binary stellar evolution on compact-object binaries.Anchoring the Chromospheric Activity$-$Rotation Relation: A Study of the Pleiades and Group X
We present a study of the rotation and the chromospheric H$α$ activity of low-mass stars in the $\approx$120 Myr-old Pleiades and the $\approx$400 Myr-old Group X open clusters.JWST observations of 47 Tucanae: I. The low-mass main sequence down to the hydrogen-burning limit
We present the first results of a series of studies based on JWST observations of the globular cluster 47 Tucanae (47 Tuc, or NGC 104) obtained with NIRCam.The mass functions of multiple stellar populations in 47 Tucanae
We used a combination of James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations to investigate the mass functions (MFs) of the different stellar populations in the globular…
