Effects of temperature-dependent optical properties on the determination of interstellar dust masses

Lapo Fanciullo, Jonathan P. Marshall, Francisca Kemper +2

Accurate measurements of interstellar dust mass are key to answering several astrophysical questions. A common method of obtaining the mass is to fit the far-infrared thermal emiss…

The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk

Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35

We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…

Testing the Impact of Planet-stirring, Self-stirring, and Mixed-stirring on Debris Disc Architecture: A Case Study of HD 16743

Jonathan P. Marshall, Marco A. Muñoz-Gutiérrez, Antranik A. Sefilian +1

Dynamical interactions between planets and debris discs can excite the orbits of embedded planetesimals to such a degree that a collisional cascade is triggered, generating detecta…

Investigating silicate, carbon, and water in the diffuse interstellar medium: the first shots from WISCI

S. T. Zeegers, Jonathan P. Marshall, Karl D. Gordon +33

The dusty interstellar medium (ISM) of the Milky Way is distributed in a complex, cloudy structure. It is fundamental to the radiation balance within the Milky Way, provides a reac…

Polarization position angle standard stars: a reassessment of and its variability for seventeen stars based on a decade of observations

Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +14

Observations of polarization position angle () standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in bo…
