Description
We present near IR photometry and spectrophotometry of two unusual novae observed in 1991: Nova Herculis and Nova Scuti. Both are seen to have unusual spectral and light curve characteristics, the former due to the very formation of a dust cloud surrounding the nova and the second because of what is interpreted to be high interstellar reddening. Both novae present strong and well defined Brackett gamma lines, although in the former this line disappeared rapidly due to blanketing from the circumstellar dust cloud. Considerable differences are seen between the visible and IR light curves of both objects. Nova Herculis is found to be the fastest nova ever observed in the visible with a time to decay 3 mag from maximum (t 3) of 2.8 d.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Long-term Study of the 2020 Magnetar-like Outburst of the Young Pulsar PSR J1846-0258 in Kes 75
    Magnetar-like activity has been observed in a large variety of neutron stars. PSR J1846‑0258 is a young 327 ms radio-quiet pulsar with a large rotational power (∼8 × 10 36 erg s ‑1), and resides at the center of the supernova remnant Kes 75. It is one of the rare examples of a high-magnetic-field pulsar showing characteristics both of magnetars and

    Constraining the overcontact phase in massive binary evolution: III. Period stability of known B+B and O+B overcontact systems
    Context. Binary systems play a crucial role in massive star evolution. Systems composed of B-type and O-type stars are of particular interest due to their potential to lead to very energetic phenomena or the merging of exotic compact objects. Aims. We aim to determine the orbital period variations of a sample of B+B and O+B massive overcontact
