Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
Darryl Z. Seligman, Marco Micheli, Davide Farnocchia +44
We report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an…
Constraints on the non-thermal desorption of methanol in the cold core LDN 429-C
A. Taillard, V. WakelaM, P. Gratier +6
Cold cores are an early step of star formation, characterized by densities > 10 cm, low temperatures (< 15 K), and very low external UV radiation. We investigate the phy…
TNO or Comet? The Search for Activity and Characterization of Distant Object 418993 (2009 MS9)
Erica Bufanda, Karen J. Meech, Jan T. Kleyna +10
2009 MS9 is a trans-Neptunian object (TNO) whose perihelion brings it close to the distance where some long period comets are seen to become active. Knowing this, and the fact that…
Compact pebbles and the evolution of volatiles in the interstellar comet 2I/Borisov
Bin Yang, Aigen Li, Martin A. Cordiner +6
The interstellar traveler, 2I/Borisov, is the first clearly active extrasolar comet, ever detected in our Solar system. We obtained high-resolution interferometric observations of…
Characterizing the Manx Candidate A/2018 V3
Caroline Piro, Karen J. Meech, Erica Bufanda +10
Manx objects approach the inner solar system on long-period comet (LPC) orbits with the consequent high inbound velocities, but unlike comets, Manxes display very little to no acti…
SN2019yvq Does Not Conform to SN Ia Explosion Models
M. A. Tucker, C. Ashall, B. J. Shappee +7
We present new photometric and spectroscopic observations of SN 2019yvq, a Type Ia supernova (SN Ia) exhibiting several peculiar properties including an excess of UV/optical flux w…
