Open Star Clusters and Their Asymmetrical Tidal Tails [PDF]
The Astrophysical JournalStars that evaporate from their star cluster by the energy equipartition process end up in either a leading or a trailing tidal tail. In Newtonian gravitation and for open star clusters in the solar vicinity, the tidal threshold, or práh, for escape is ...

Giant tidal tails of helium escaping the hot Jupiter HAT-P-32 b. [PDF]
Sci Adv, 2023 Capturing planets in the act of losing their atmospheres provides rare opportunities to probe their evolution history. This analysis has been enabled by observations of the helium triplet at 10,833 angstrom, but past studies have focused on the narrow ...

The Spectacular Tidal Tails of Globular Cluster M3 (NGC 5272) [PDF]
The Astrophysical Journal, 2023 We provide a detailed analysis of the tidal tails of the globular cluster M3 (NGC 5272). We first discover clear extratidal structures with a slight S shape near the cluster. This inspires us to examine the existence of its long tidal tails. We highlight

Surviving Tidal Tails Around the Milky Way Bulge Globular Cluster NGC 6355 [PDF]
The Astronomical JournalWe present results of the analysis of a set of images obtained in the field of the Milky Way bulge globular cluster NGC 6355 using the Dark Energy Camera, which is attached to the 4 m Blanco telescope of the Cerro-Tololo Interamerican Observatory.

Modeling Tidal Streams and Tidal Tails around Galaxies Using Deep Wendelstein Imaging Data [PDF]
The Astrophysical JournalFrom the Λ cold dark matter paradigm, it is expected that galaxies merge and grow in their environments. These processes form various tidal features depending on the merger mass ratio, orbital parameters, and gas richness. We inspected 170 $g^{\prime} $ -

The Multiple Extended Tidal Tails of NGC 288 [PDF]
The Astrophysical JournalUsing photometry and proper motions from Pan-STARRS, DECaLS, and Gaia Data Release 3, we detect a ∼35°–70° long trailing stellar debris stream associated with the globular cluster NGC 288.

Flipping of the Tidal Tails of the Ophiuchus Stream due to the Decelerating Galactic Bar [PDF]
The Astrophysical JournalThe Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shorter than expected angular extent given its old stellar population and ...

APOGEE physical properties of globular cluster tidal tails
Astronomy & AstrophysicsA recent model prediction claimed that there is a correlation between the formation scenarios of globular clusters (i.e., whether they formed in situ or in dark matter halos that were accreted into the Milky Way) and some properties of their tidal tails,

Revisiting Physical Properties of Mock Globular Cluster Tidal Tails
The Astrophysical JournalIn this work, we present results of the first in-depth analysis of extra-tidal mock stars of Milky Way globular clusters recently generated by S. M. Grondin et al.

Confirming the Tidal Tails of the Young Open Cluster Blanco 1 with TESS Rotation Periods
The Astrophysical JournalBlanco 1 is an ≈130 Myr open cluster located 240 pc from the Sun, below the Galactic plane. Recent studies have reported the existence of diffuse tidal tails extending 50–60 pc from the cluster center based on the positions and velocities measured by ...
