Host-star metallicities and kinematics of directly imaged brown-dwarf companions
C. Swastik, R. K. Banyal, M. Muduli +15
Brown dwarfs are common as free-floating objects but rare as close companions to Sun-like stars, a disparity known as the "brown-dwarf desert". Host-star metallicity can constrain…
A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2
C. Swastik, M. Bestha, L. S. Sonith +11
WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…
The Companions to B and A Stars Snapshot (C-BASS) Survey: I. Discovery of a Young Brown Dwarf Companion to HIP 17453
Marah Brinjikji, Adam J. Smith, Jennifer Patience +26
We report the detection of a new brown dwarf companion to HIP 17453 A, a chemically peculiar A0V star located at a distance of 81 pc. HIP 17453 A was observed with high-resolution…
Two inner dust clumps in PDS 70. A third protoplanet traced by trojan material or a substructured inner disk?
O. Balsalobre-Ruza, V. Christiaens, N. Huélamo +18
The PDS 70 cavity hosts two confirmed directly imaged protoplanets and a third inner planet candidate at 13au, labeled PDS 70 d. Despite its Keplerian motion, its unusually blue sp…
The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization
V. Squicciarini, S. Desidera, G. Chauvin +109
Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…
Imaging the LkCa 15 system in polarimetry and total intensity without self-subtraction artefacts
C. Swastik, Zahed Wahhaj, Myriam Benisty +7
Studying young protoplanetary disks is essential for understanding planet formation, but traditional angular differential imaging can introduce self-subtraction artefacts that hind…
