TOI-1994b: A Low Mass Eccentric Brown Dwarf Transiting A Subgiant Star
Emma Page, Joshua Pepper, Duncan Wright +22
We present the discovery of TOI-1994b, a low-mass brown dwarf transiting a hot subgiant star on a moderately eccentric orbit. TOI-1994 has an effective temperature of $7700^{+720}_…
Polarimetric detection of nonradial oscillation modes in the beta Cephei star beta Crucis
Daniel V. Cotton, Derek L. Buzasi, Conny Aerts +11
Here we report the detection of polarization variations due to nonradial modes in the beta Cephei star beta Crucis. In so doing we confirm 40-year-old predictions of pulsation-indu…
The near-core rotation of HD 112429: a gamma Doradus star with TESS photometry and legacy spectroscopy
T. Van Reeth, P. De Cat, J. Van Beeck +8
The TESS space mission provides us with high-precision photometric observations of bright stars over more than 70% of the entire sky, allowing us to revisit and characterise well-k…
The Surface Magnetic Activity of the Weak-Line T Tauri Stars TWA 7 and TWA 25
B. A. Nicholson, G. Hussain, J. -F. Donati +6
We present an analysis of spectropolarimetric observations of the low-mass weak-line T Tauri stars TWA 25 and TWA 7. The large-scale surface magnetic fields have been reconstructed…
The wavelength dependence of interstellar polarization in the Local Hot Bubble
Daniel V. Cotton, Jonathan P. Marshall, Priscilla C. Frisch +6
The properties of dust in the interstellar medium (ISM) nearest the Sun are poorly understood because the low column densities of dust toward nearby stars induce little photometric…
The Surface Magnetic Activity of the Weak-Line T Tauri Stars TWA 9A and V1095 Sco
B. A. Nicholson, G. A. J. Hussain, J. -F. Donati +5
We present a detailed analysis of high-resolution spectropolarimetric observations of the weak-line T Tauri stars (wTTSs) TWA 9A and V1095 Sco as part of a wider sur- vey of magnet…
