JWST Spectroscopy of (142) Polana: Connection to NEAs (101955) Bennu and (162173) Ryugu Open
The new Polana collisional family is the hypothesized origin of the near-Earth asteroids (101955) Bennu, which was the target of the NASA OSIRIS-REx mission, and (162173) Ryugu, which was the target of the JAXA Hayabusa2 mission. We presen…

Rotationally Resolved Near-infrared Spectroscopy of Three Large Eurybates Family Members Open
The Eurybates family is the largest collisional family in the Jupiter Trojan population. Previous visible spectroscopy of asteroid (3548) Eurybates has shown potential surface heterogeneity due to rotation of the asteroid. New near-infrare…

Stringent upper limits of minor species at the cloud top of Venus: PH<sub>3</sub>, HCN, and NH<sub>3</sub> Open
Aims. Following several reports announcing the detection or non-detection of minor species above the clouds of Venus, we have searched for other possible signatures of PH 3 , HCN, and NH 3 in the infrared range. Methods. Since 2012, we hav…

Origin of Asteroid (101955) Bennu and its Connection to the New Polana Family Open
The asteroid (142) Polana is classified as a B-type asteroid located in the inner Main Belt. This asteroid is the parent of the New Polana family, which has been proposed to be the likely source of primitive near-Earth asteroids such as th…

Ground-based thermal mapping of Venus:  HDO and SO2 monitoring and upper limits of NH3, PH3 and HCN at the cloud top Open
As part of a long-term monitoring program, full disk thermal maps of HDO (near 7 microns) and SO2 (near 7 and 19 microns) have been obtained at the cloud top of Venus in 2023, using the TEXES(Texas Echelon Cross-Echelle Spectrograph) …

Rotationally Resolved Mid-infrared Spectroscopy of (16) Psyche Open
Asteroid (16) Psyche is theorized to be an exposed iron core of a primordial asteroid and is the target of the upcoming NASA Psyche mission. Recent observations of Psyche identified the presence of rotational heterogeneity, a fine-grained …

Detection of Molecular H<sub>2</sub>O on Nominally Anhydrous Asteroids Open
We used the FORCAST instrument on SOFIA to obtain mid-infrared spectra (4.9–13.7 μ m) of four S-type asteroids: (7) Iris, (11) Parthenope, (18) Melpomene, and (20) Massalia. Three of these four silicate-rich asteroids (Iris, Melpomene, and…
