Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS

Y. Carteret, V. Bourrier, L. Parc +57

The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…

The Variation of Circumstellar Parameters through Early Stellar Evolution

Michael Connelley, Christian Flores, Bo Reipurth

We report on the evolution of extinction, mass accretion rate, and spectral index from analysis of SpeX observations and AllWISE spectral energy distributions, compared to stellar…

What the Solar System Can Teach Us About Rocky Exoplanets

Paul K. Byrne, Claire Marie Guimond, Peter A. Cawood +9

The number of rocky extrasolar planets being discovered continues to increase, but so too does the apparent diversity of such worlds. As we work to understand the likely bulk prope…

ALMA Reveals an Explosive Outflow Candidate in IRAS 16119--5048

Yongquan Luo, Jianjun Zhou, Tie Liu +24

We present a multiwavelength study of the massive star formation region IRAS 16119-5048 (I16119) using ALMA ATOMS Band 3 and QUARKS Band 6 observations, complemented by archival AT…

An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter

Yao Wang, Yichen Zhang, Rubén Fedriani +14

Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…

Constraining the orbit of the retrograde planet in the Octantis system

Alan Cefali Signor, Alexandre C. M. Correia, Maria Helena Moreira Morais +4

The Octantis system is composed of a compact stellar binary and a retrograde S-type planet orbiting near the edge of stability. Here, we investigate the dynamically viable arch…
