# V386 Pup

V386 Pup is a B4V blue-white main-sequence [star](https://spacecatalog.org/stars) in the constellation [Puppis](https://spacecatalog.org/constellation/puppis), shining at apparent magnitude 8.73 (V). Other catalogues list it as HD 62738 and HIP 37668.

## At a glance

- **WHAT IT IS:** Blue-white main-sequence star
- **HOW BRIGHT (V):** 8.73 — Binoculars reach it; the naked eye does not.
- **WHERE TO LOOK:** [Puppis](https://spacecatalog.org/constellation/puppis) — The patch of sky it sits in, as seen from Earth.

## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Spectral type | B4V |
| Surface temperature | 16 134 K |
| Luminosity (bolometric) | 1995.0835 L☉ |
| Radius | 5.606 R☉ |
| Mass | 6.034 M☉ |
| Surface gravity (log g) | 3.705 |
| Variability | SX Arietis rotating variable |
| Variability type (GCVS) | SXARI: |

### HOW BRIGHT IT IS

What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

| Field | Value |
| --- | --- |
| Colour index (B−V) | −0.074 |
| Variable magnitude, brightest | 8.66 |
| Variable magnitude, faintest | 8.84 |

### WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.

| Field | Value |
| --- | --- |
| Proper motion (RA) | −3.84 mas/yr |
| Proper motion (Dec) | 8.15 mas/yr |
| Radial velocity | 0 km/s |

### OTHER NAMES AND NUMBERS

The identifiers other catalogues file this object under, for anyone joining this data to theirs.

| Field | Value |
| --- | --- |
| Variable-star designation | V386 Pup |

### WHERE THESE FIGURES CAME FROM

Which catalogue, paper or model each of the fields above was read from, where the source named one.

| Field | Value |
| --- | --- |
| Spectral type from | SIMBAD (1978MSS...C02....0H, quality C) |
| Stellar parameters from | Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate |
